Space Saving CRBF Crossed Roller Bearings for Semiconductor Automation

What are CRBF Crossed Roller Bearings?

CRBF crossed roller bearings are compact,high-rigidity precision bearings featuring cylindrical rollers arranged crosswise at right angles between an inner and outer ring.

Available precision grades cover P5,P4 and ultra-precision P2.Metric dimension range includes inner diameter from 10 mm to 115 mm,outer diameter from 52 mm to 240 mm and cross-section height from 8 mm to 28 mm.

Bearing rings and rolling elements adopt GCr15 high carbon chromium steel with surface hardness HRC 60-62.SUS440C stainless steel material is available for corrosion resistant working environments.Cage choices include Nylon 66 for lightweight low friction performance,brass for high speed heavy duty operation and custom composite materials.Sealing solutions include open type for clean high speed working conditions and contact rubber seals UU or U for dust and splash protection in dusty humid industrial settings.

Standard models can be shipped within 7-15 working days.Custom service supports flange dimension adjustment,bore modification,ceramic roller hybrid design,stainless steel upgrade and special lubricant formulas for vacuum or high temperature conditions.Custom lead time will be evaluated based on drawing complexity and raw material supply status.

The Features of CRBF Crossed Roller Bearings

Integral Mounting Holes:Pre-drilled counterbored and female-threaded holes on both rings enable direct bolting to mating components.No specialized housings or external retaining plates required.

Solid One-Piece Rings:Solid inner and outer rings minimize structural deformation and maintain high rotational runout accuracy.

90°Orthogonal Line Contact:Cylindrical rollers alternate at right angles inside a precision V-groove raceway.A single bearing absorbs radial,double-direction thrust,and heavy tilting moment loads simultaneously.

Ultra-Compact Cross-Section:Low sectional height and narrow width maximize space efficiency in compact rotary mechanisms.

Synthetic Separators:Polymer spacers between individual rollers eliminate roller-to-roller friction and skewing,lowering operational torque and heat generation.

Factory Preload Options:Available with pre-set negative clearance for zero-backlash operation and high rotational stiffness out of the box.

Sealed Enclosure:Dual synthetic rubber seals protect internal raceways from dust,chips,and moisture.
