The LYDL RE5013 cross roller bearing combines a 50 mm bore, 80 mm outside diameter and 13 mm width in a compact 0.27 kg assembly. Its split inner ring and one-piece outer ring suit mechanisms requiring accurate outer-ring rotation.
Catalogue basic radial load ratings are 16.7 kN dynamic and 20.9 kN static. Specify accuracy, clearance or preload, sealing and lubrication to match your assembly. Request a quotation with your quantity and delivery country.
RE5013 Cross Roller Bearing Overview
The LYDL RE5013 cross roller bearing measures 50 × 80 × 13 mm and weighs approximately 0.27 kg. Its split inner ring and one-piece outer ring suit compact mechanisms requiring accurate outer-ring rotation.
The crossed rollers support radial loads, axial loads in both directions and overturning moments within one bearing. Browse the RE series cross roller bearings for the wider size range.

Numerical values above are catalogue references cross-checked against the LYDL RE model table and THK RE catalogue, page A18-27. C and C₀ are radial ratings, not direct allowable axial loads or payloads. Final selection also considers overturning moment, duty cycle, mounting stiffness, lubrication and required life.
Comparison values follow the THK RE catalogue; masses are approximate.
RE4010: The smallest envelope here, with a 10 mm bearing width.
RE5013: A 50 mm bore and higher catalogue radial ratings than RE4010, requiring 3 mm more bearing width.
RE6013: A 60 mm bore at the same 13 mm width, but a larger 90 mm outside diameter.
RE6013 provides approximately 7.8% more dynamic radial rating than RE5013. That increase does not establish the same percentage improvement in allowable payload or service life. Get an RE5013 quotation — Send your quantity and delivery country; add the required accuracy grade if known.
Applications for Compact Outer-Ring Rotation
Consider RE5013 when a fixture or platform rotates around a stationary central support and the bearing must fit an 80 mm outside diameter.
Rotary inspection fixtures: Rotating workpieces around a fixed centre while supporting combined loads.
Sample indexing tables: Compact rotary support for laboratory or automated handling stations.
Optical positioning stages: Supporting rotating sensor or optical assemblies where mounting accuracy is controlled.
Evaluate these application concepts against actual loads, speed, environment and the complete mounting design.

Rotational accuracy grades; dimensional tolerances require separate confirmation
For precision positioning, specify the required outer-ring runout and measurement datum, alongside the grade. Select lubricant and clearance with the operating speed, temperature and starting-torque requirement.
Use the approved shaft, housing and retention design. Tighten flange bolts progressively in a diagonal sequence, then check rotation and runout after clamping. THK assembly guidance provides the general mounting procedure.
Inspection and Protective Packaging
LYDL coordinates production and inspection against the agreed drawing and technical requirements. For RE5013, agree the dimensional checks, outer-ring runout and clearance or preload acceptance criteria before production.
Inspection reports and material records can be agreed with the order. See LYDL manufacturing and quality control for the factory’s process and documentation approach.
Specify corrosion protection, individual bearing packaging and the outer carton or protective case to suit the shipment.
RE5013 FAQ
1. Does the 13 mm width include the complete mounting assembly?
No. The 13 mm dimension is the bearing width. Retaining flanges, supporting shoulders and other assembly components require additional space according to the mounting design.
2. Is the entire 50 mm bore available for cables or tubing?
The 50 mm dimension is the bearing’s nominal bore. A shaft, hub or retaining arrangement can reduce the usable passage, so confirm the clear opening in the complete assembly.
3. What does the 66 mm roller pitch circle describe?
It describes the circle through the roller centres, not a mounting bolt pattern. Use the approved LYDL mounting drawing to define the shaft, housing and retaining components.
4. How should I specify a single-sealed RE5013U?
Specify which face receives the seal: the marked or unmarked face under the THK convention. Confirm its orientation against the mounting datum and the side exposed to contamination. UU denotes seals on both faces.
5. Which model should I consider if the 50 mm shaft rotates?
Compare RB5013 cross roller bearing. It shares the 50 × 80 × 13 mm boundary dimensions but uses a one-piece inner ring for applications prioritising inner-ring rotational accuracy. Confirm the mounting geometry and configuration before substitution.
