New Original Rexroth R162281422 Runner Block Ball Bearing
Product Overview
R162281422 is a brand-new original Bosch Rexroth SNS slimline ball runner block belonging to Rexroth Ball Rail linear guide system. This 20-size standard-height normal-length ball carriage adopts a four-row circular ball circulation design, manufactured from high-strength precision carbon steel. Matched with corresponding Rexroth 20-size linear guide rails, it delivers stable low-friction linear motion. This model is configured with C1 moderate preload, N normal accuracy class and DS double-lip sealing structure, equipped with ball retainer chain to prevent steel ball falling off. It is widely used in automated assembly equipment, packaging machinery, printing machines, electronic production lines, testing equipment and general factory automation equipment that requires medium rigidity and smooth reciprocating movement.

Main Functions
- Single-axis constrained linear guidance: Limit movement to straight travel and restrain lateral offset under high-speed reciprocating operation.
- Multi-directional load bearing: Capable of bearing radial, reverse radial and horizontal lateral loads simultaneously with balanced load capacity.
- Moment load resistance: Support pitching, yawing and rolling moment loads to realize single-runner-block installation solutions.
- Low-friction rolling motion: Rolling contact design reduces driving force and energy consumption compared with sliding guide structures.
- Enhanced dustproof and anti-splash performance: Double-lip DS seals block metal chips, dust and tiny liquid splashes entering ball circulation area.
- Anti-drop ball chain design: Prevent steel balls from spilling out when the runner block is detached from the guide rail.
- Convenient re-lubrication: Reserved lubrication port for regular grease replenishment to extend service life.
- High interchangeability: Freely matched with all standard 20-size Rexroth SNS guide rails without selective pairing.
Technical Features
- Optimized circulation channel contour ensures smooth ball circulation, low running noise and minor vibration during frequent reciprocation.
- Precision ground raceway surface improves motion straightness and prolongs fatigue service life under cyclic loads.
- Compact slimline structure saves horizontal installation space for equipment with limited layout space.
- Moderate C1 preload eliminates motion clearance and improves rigidity without causing excessive friction loss.
- Standardized top mounting threaded holes support flexible installation directions and convenient replacement.
- Factory pre-lubrication allows direct commissioning after installation without initial grease filling.
- High hardness raceway surface provides outstanding wear resistance for continuous 24-hour industrial operation.
- Modular platform design supports quick switching between different accuracy grades and preload variants within the same size series.
