CXE Stainless Steel Ball Bearing Track Rollers (SLR Series)
Precision rollers for linear motion and track guidance systems
Ball Bearing Track Rollers
Ball bearing track rollers from CXE Bearing are single or double row rolling bearings based on deep groove or angular contact ball bearing designs for direct mounting. Our stainless steel bearing rollers provide reliable performance in demanding linear motion applications.
Design Features
- Construction: Single or double row design with thick-walled outer ring
- Surface: Spherical or cylindrical outer surface
- Mounting: Available with or without studs (studless versions mount directly on shafts)
- Sealing: Double-sided seals for contamination protection
- Installation: Runs directly on smooth tracks (no housing required)
Performance Characteristics
- High radial load capacity with moderate axial load capability
- Compensates for minor misalignment and track irregularities
- Double-row stud-type rollers feature adjustable eccentric collars for precise clearance control
- Corrosion-resistant stainless steel construction
- Maintenance-free operation with integral seals
Typical Applications
LR Bearing track rollers are ideal for:
- Cam mechanisms and cam followers
- Machine tool guideways and linear slides
- Conveyor systems and material handling equipment
- Linear guidance systems
- Packaging machinery
- Printing equipment
- Automated production lines
