The RE8016 cross roller bearing from LYDL measures 80 × 120 × 16 mm and uses a split inner ring with a one-piece outer ring for precision outer ring rotation. Its crossed rollers support radial, axial and moment loads in one assembly. Reference radial load ratings are 30.1 kN dynamic and 42.1 kN static, with an approximate mass of 0.70 kg. Specify seals, preload and accuracy requirements when requesting a drawing and quotation.
RE8016 Cross Roller Bearing for Precision Outer Ring Rotation
The RE8016 cross roller bearing measures 80 × 120 × 16 mm. Its split inner ring and one-piece outer ring suit applications requiring precision outer ring rotation, consistent with THK’s RE design guidance.
Within LYDL’s cross roller bearing range, RE8016 combines an 80 mm shaft bore with a 16 mm bearing width. Its crossed rollers support radial, axial and moment loads in one compact assembly.

Seals, Preload and Ordering Details
A reference designation is RE8016UUCC0P4:
UU: seals on both sides; U indicates one-side sealing.
CC0: preloaded radial-clearance class; C0 and C1 indicate positive-clearance classes in THK coding.
P4: rotational accuracy designation in THK coding. Dimensional accuracy must be specified separately.
LYDL lists P5, P4 and P2 options. Confirm the required runout limits, clearance, grease and inspection conditions with your order; a suffix alone does not define installed machine accuracy. See THK’s designation guide. Request an RE8016 drawing and quotation Send your quantity, mating-part drawing and operating conditions to confirm configuration, price and delivery time.
RE10016 increases the bore by 20 mm, but its basic dynamic radial rating is only about 5% higher. Select it for the required geometry and verified load case; increasing bore size alone does not establish suitability for a higher overturning moment.
RE8016 Applications
RE8016 is a candidate for compact rotary mechanisms where the outer ring carries the moving platform or housing. Selection depends on combined loads, available space and required rotational accuracy.
Precision rotary tables: support a rotating fixture around a stationary central shaft.
Automation indexing systems: use the 16 mm bearing width where axial installation space is limited.
Optical inspection equipment: support rotating workpiece stages, with runout requirements defined for the complete assembly.
Robotic rotary axes: accommodate rotating housings around an 80 mm shaft interface, subject to moment-load and torque verification.
The 80 mm bearing bore is the shaft interface. In a hollow-shaft arrangement, shaft wall thickness and retention components determine the usable central passage.
Mounting Considerations
Use rigid, accurately machined shaft and housing seats. Keep the matched inner-ring sections together and support them correctly. Tighten presser-flange bolts progressively in a cross pattern, then check rotational torque and runout after assembly.
Follow the approved LYDL drawing and the THK assembly procedure. Bolt torque depends on the actual flange, fasteners and joint design.
RE8016 Inspection and Packaging
For RE8016 orders, agree on dimensional tolerances, rotational runout limits and any required torque measurements before production. Define the test conditions so inspection results can be assessed against your application requirements.
Packaging can include corrosion protection, individual wrapping, cushioning and an outer shipping case. Confirm the packing method and model identification with the order.
RE8016 FAQ
Does the 80 mm bore provide an 80 mm clear passage after installation?
Not necessarily. The bearing bore fits the shaft; a hollow shaft’s wall, shoulders and retention components reduce the usable opening. Send the required clear-passage diameter with your assembly drawing.
Does RE8016 have mounting bolt holes?
The standard RE8016 design has no integral mounting bolt holes. It requires suitable shaft/housing shoulders and retention components. Lubrication holes must not be treated as fixing holes.
Does RE8016UUCC0 guarantee low starting torque?
No. Seals, preload, grease, temperature and mounting fits affect starting torque. If motor sizing or slow indexing is critical, specify an acceptable torque range and the conditions under which it should be measured.
Can I use 30.1 kN as the allowable rotary-table payload?
No. This is the basic dynamic radial load rating, not an allowable axial payload or moment rating. Selection needs radial and axial forces, overturning moment, speed, duty cycle and required life. ISO 281 explains the load-rating and rating-life framework.
Can LYDL RE8016 replace THK RE8016 or RB8016?
A THK RE8016 reference requires checks of dimensions, shoulders, seals, preload and accuracy against the LYDL drawing. RB8016 has the same main envelope but a different split-ring arrangement intended primarily for precision inner ring rotation. Confirm the rotating ring and mounting arrangement before substitution.
