Improve Rotary Accuracy with CRBS Crossed Roller Bearings

What are CRBS Crossed Roller Bearings?

CRBS series crossed roller bearings are ultra-thin crossed roller bearings engineered specifically for applications with strict radial space and weight constraints.

This series adopts flange integrated inner ring with pre-machined standard mounting holes and integral outer ring structure.Precision grades cover P5,P4 and ultra-precision P2.Inner diameter ranges from 50 mm to 200 mm,outer diameter covers 66 mm to 226 mm and cross-section height varies from 8 mm to 13 mm.

Bearing rings and rolling elements can choose GCr15 high carbon chromium steel or SUS440C stainless steel for corrosion resistant working conditions.Cage options include brass and reinforced Nylon 66.Multiple sealing solutions are available.Open type suits clean low-speed heavy load conditions which need periodic external lubrication.Contact rubber seals UU or U provide dust and splash protection for dusty humid industrial sites.Labyrinth seals ZZ deliver superior shielding for high-impact heavy-duty environments.

Standard product delivery takes 7 to 15 working days.Custom service supports non-standard dimension adjustment,flange parameter modification,heavy load optimized design,special lubricant for extreme temperature and labyrinth seal upgrade according to project requirements.

The Features of CRBS Crossed Roller Bearings

Ultra-Slim Cross-Section:Exceptionally thin section height relative to bore size,reducing mass and footprint compared to standard RB series bearings.

Split Outer Ring/Solid Inner Ring:The outer ring is divided circumferentially into two separate halves,while the inner ring is a single continuous piece.Optimized for high-precision inner-ring rotation.

90°Orthogonal Roller Line Contact:Cylindrical rollers alternate at right angles inside precision V-grooves,enabling a single bearing to absorb radial,bi-directional axial,and moment loads simultaneously.

Synthetic Spacers:Roller separators prevent roller-to-roller friction and skewing,providing uniform torque and smooth rotation.

Factory-Set Preload Options:Available in preloaded (CC0) or small-clearance (C1/C0) variants to achieve zero-backlash operation and high structural rigidity.
