YRT580 Rotary Table Bearing | 580 × 750 × 90 mm

YRT580 Rotary Table Bearing for Rotary and Swivel Assemblies

The LYDL YRT580 rotary table bearing has a 580 × 750 × 90 mm installation envelope. Two axial roller rows support axial forces in opposite directions, while a radial roller row provides radial support. The combined arrangement also supports tilting moments. Within the YRT rotary table bearing range, YRT580 increases the bore by 120 mm and height by 20 mm compared with YRT460. Its outer-ring fixing-hole count changes from 45 to 42, and its fixing-hole diameter increases to Ø11.4 mm. YRT series construction reference. YRT580 nominal dimensions: 580 × 750 × 90 mm.

Dimensions: Schaeffler Reference and LYDL Listing

The reference column follows INA/Schaeffler YRTC580-XL in TPI 120; the LYDL column follows the published YRT580 series table. These source values are shown separately where they differ.

Dimension	YRTC580-XL reference	LYDL YRT580 listing
Bore, d	580 mm	580 mm
Outside diameter, D	750 mm	750 mm
Overall height, H	90 mm	90 mm
Mounting heights, H1 / H2	60 / 30 mm	60 / 30 mm
Outer-ring width, C	30 mm	30 mm
Inner-ring profile diameter	D1 max. = 700 mm	d1 = 700 mm
Inner fixing-hole pitch circle	J = 610 mm	dn = 610 mm
Outer fixing-hole pitch circle	J1 = 720 mm	dm = 720 mm
Inner-ring fixing holes	46 × Ø11.4 mm	46 × Ø11.4 mm
Counterbore diameter	d2 = 18 mm	ds = 18 mm
Counterbore depth	a = 11 mm	Ts = 11.4 mm
Outer-ring fixing holes	42 × Ø11.4 mm	42 × Ø11.4 mm

Counterbore difference: Schaeffler specifies 11 mm depth; LYDL’s table lists 11.4 mm. The approved LYDL order drawing must resolve this feature before manufacture or replacement approval. Equal nominal dimensions elsewhere do not establish identical tolerances or complete interchangeability. LYDL lists P5, P4 and P2 precision options, grease lubrication, and GCr15, GCr15SiMn or 100Cr6 bearing steel. Specify the selected grade separately; these materials are not automatic equivalents.

INA/Schaeffler YRTC580-XL Performance Reference

The following figures are TPI 120 reference data for YRTC580-XL. LYDL can review custom requirements based on these benchmarks; achieved performance must be defined in the agreed supply specification.

Reference parameter	YRTC580-XL — TPI 120
Basic dynamic axial load rating, Ca	580 kN
Basic static axial load rating, C0a	4,450 kN
Basic dynamic radial load rating, Cr	235 kN
Basic static radial load rating, C0r	730 kN
Continuous-operation limiting speed	80 rpm
Swivel-operation limiting speed	200 rpm; separate duty assessment required
Frictional torque guide value, MR	60 N·m at 5 rpm
Mass	89 kg
Standard fitted axial / radial runout	10 / 10 µm with ideal adjacent construction

The catalog’s continuous-speed conditions include prescribed grease distribution, rigid screw mounting and no external application load. Permissible operating speed still depends on loads, duty cycle and heat dissipation. Static ratings are not allowable workpiece weights, and the friction guide value alone does not size the drive motor. Online versus PDF: Schaeffler’s online YRTC580-XL product data give 85.2 kg, while TPI 120 gives 89 kg. Neither value establishes LYDL’s supplied mass. Temperature: The online brand page gives a +120°C maximum; TPI 120 states −30°C to +100°C. LYDL’s series page states −20°C to +120°C. Specify the required operating range with the grease and construction, rather than combining these limits. Need the mounting drawing or a custom specification? Request a YRT580 technical review. Begin with the model, quantity and application. Add a drawing, loads, offsets, speed and precision targets when detailed selection is required.

YRT580 Application Areas

Consider this size where a 580 mm bore and 750 mm outside diameter fit the machine layout:

• CNC rotary workholding: support for fixtures and workpieces under combined machining loads.
• Swivel assemblies: positioning axes with changing gravity and cutting-force directions.
• Indexing fixtures: repeated angular movements with specified acceleration and settling.
• Measuring platforms: rotary inspection with defined running accuracy and structural deflection.

Include the complete fixture and workpiece geometry in the load review. For offset loading, the distance between the applied force and bearing reference point can be as important as the force magnitude. Application illustrations for YRT selection; assess YRT580 using the complete fixture and operating cycle.

Comparing Nearby YRT Models

Model	Bore × OD × height	Installation consideration
YRT460 rotary table bearing	460 × 600 × 70 mm	Smaller housing and 20 mm less height
YRT580	580 × 750 × 90 mm	580 mm bore with a 90 mm axial envelope
YRT650 rotary table bearing	650 × 870 × 122 mm	70 mm more bore; 32 mm additional height

These dimensions help establish the layout. A larger model is not automatically preferable: verify its radial and axial ratings, moment capability, stiffness and mounting requirements for the actual load case.

YRTS580, YRTM580 and the ZKLDF Route

Option	Main function	Relevance to a 580 mm project
LYDL YRT580	Axial/radial roller support	Base envelope: 580 × 750 × 90 mm
LYDL YRTS580	Higher-speed roller-bearing family	Listed model; obtain the supply drawing
LYDL YRTM580	Bearing system with angular measurement	Listed model; define the complete measuring interface
ZKLDF family	Double-direction angular contact ball support	No Schaeffler ZKLDF580 verified in the reviewed catalog

LYDL names YRTS580 and YRTM580 in its model lists, although its detailed dimensions do not cover these configurations. Their availability and specifications should be established through the offered drawing, not inferred from the table’s endpoint. Schaeffler YRTS580-XL is listed in TPI 120 at 580 × 750 × 90 mm, with a 350 rpm limiting speed under catalog conditions. This provides a higher-speed reference, not a LYDL performance commitment. The reviewed TPI 120 ZKLDF tables extend through ZKLDF460, whose 460 × 600 × 70 mm envelope does not match YRT580. A ball-bearing solution for the 580 mm installation requires a verified model and drawing, followed by checks of interfaces, stiffness, preload, lubrication, sealing and duty.

Specification, Inspection and Protective Packing

Specify numerical tolerances alongside P5, P4 or P2. In the Schaeffler reference system, XL denotes X-life, VSP addresses preload for an axially supported L-section ring, and PRL50 denotes restricted runout. TPI 120 directs customers to consult Schaeffler for restricted versions above 460 mm bore. Identify fixing holes, retaining screws, extraction threads and lubrication passages separately. Their functions are not interchangeable. Use the supplied mounting instructions for screw selection and tightening; do not derive a torque from hole diameter. Inspection requirements can include dimensions, hole geometry, runout and rotational resistance. Define measurement conditions and report scope with the order. Bearing runout does not establish complete-machine angular positioning accuracy. For wooden-case packing, the bearing is laid flat with rust-preventive wrapping, cushioning and suitable blocking. Tape secures the wrap; separate restraint limits movement within the case. Final packaging and the model label follow the agreed shipment configuration. Inspection and packing illustrations showing protective flat packing; these are not YRT580 batch inspection or shipment records.

YRT580 FAQ

Can a rotary table run continuously at the 200 rpm reference speed?

No. TPI 120 separates YRTC580-XL’s 80 rpm continuous-operation limit from its 200 rpm swivel-operation value. Reversing rotation does not by itself qualify a cycle for the higher figure. Provide the movement angle, speed profile, dwell time and thermal conditions for assessment.

Should the 42 outer fixing holes be spaced at 360° divided by 42?

No. The reference YRTC580-XL drawing uses a 48-position, 7.5° pitch pattern and separately identifies 42 outer fixing holes and six M12 extraction threads. Use the complete hole map. Do not replace the specified pattern with 42 equally spaced fixing positions.

Can YRT460 axial tolerances be reused when designing for YRT580?

No. TPI 120 gives standard YRTC580-XL H1 and H2 tolerances of ±0.25 mm, versus ±0.06 mm and ±0.03 mm for YRTC460-XL. These are brand reference tolerances. Establish the LYDL assembly’s axial tolerance stack using the agreed drawing and required table datum.

Can LYDL customize YRT580 around the brand reference requirements?

LYDL can review a requested specification covering dimensions, precision, lubrication and performance targets. Identify which requirements are essential and provide the operating conditions. The quotation and approved technical agreement should state the accepted values, inspection methods and any differences from the reference product.
