6. Selection Suggestions & Precautions

6.1 Selection Suggestions

1. Load & Speed Matching: REXROTH R161924051 is ideal for applications with radial loads up to 190 kN and speeds up to 5 m/s; for lighter loads (≤120 kN), select Rexroth R161921051 (35 mm profile) to reduce costs.
2. Environment Adaptation: Choose the high-temperature option (-40°C to +120°C) for foundry or furnace-side applications; opt for stainless steel components for food/beverage or cleanroom environments.
3. Accessory Compatibility: Pair REXROTH R161924051 with Rexroth’s centralized lubrication systems (e.g., R900912232) for extended maintenance intervals, and side seals for dusty or wet environments.

6.2 Precautions

1. Installation Guidelines: Align guide rails to within 0.02 mm/m straightness to avoid premature wear of REXROTH R161924051; torque mounting bolts to 80 N·m (M12) for secure fixation.
2. Lubrication Requirements: Lubricate REXROTH R161924051 with Rexroth-approved lithium-based grease (e.g., Mobil SHC 100) every 500 operating hours; avoid mixed lubricant types to prevent friction buildup.
3. Contamination Protection: Clean guide rails and carriage scrapers weekly in harsh environments (e.g., machining); replace scrapers every 12 months to maintain contamination resistance.
4. Maintenance Checks: Inspect ball bearings and raceways for wear or damage every 6 months; replace REXROTH R161924051 if radial play exceeds 0.05 mm to ensure positioning accuracy.
