The NUTR50110-A INA is a heavy-duty support roller bearing with flange design, widely recognized in the bearing industry for high load capacity, rigid structure and outstanding running stability. As a classic INA cam follower and track roller bearing, it is engineered for heavy radial load, continuous rolling and harsh working conditions, ideal for mechanical transmission and linear guide systems.
Dimensional parameters comply with ISO standard: bore diameter 50 mm, outer diameter 110 mm, overall width 32 mm, flange width 12 mm, standard chamfer 1.0×45°, tolerance grade P6, normal radial clearance CN. All dimensional indexes strictly follow INA factory standards and international rolling bearing specifications.
Material configuration adopts high-grade bearing steel: inner ring and outer ring apply 52100 chrome bearing steel, overall quenched hardness HRC 60–62, featuring excellent wear resistance, contact fatigue resistance and structural stability. Rolling bodies use high-precision bearing steel balls; the reinforced plastic retainer offers low noise, self-lubricating property and anti-deformation performance under high load.
Core manufacturing processes include precision forging, CNC turning, vacuum quenching and tempering, precision grinding and raceway superfinishing. Forging optimizes internal metal fiber flow; heat treatment eliminates residual stress and improves hardness uniformity; superfinishing reduces surface roughness, lowering friction and extending service life significantly.
Calculated per ISO 281 bearing life standard, the NUTR50110-A INA achieves L10 rated life up to 48,000 hours under standard rated load and normal lubrication. Service life is mainly affected by actual load magnitude, operating speed, ambient temperature, lubrication condition and mounting alignment accuracy.
Typical application industries cover machine tools, construction machinery, material handling equipment, automated production lines, packaging machinery and logistics conveying systems. Its thickened outer ring and flange structure can withstand impact load and lateral force, perfectly suitable for track operation, cam transmission and linear support scenarios.
Daily maintenance requires lubrication inspection every 250 working hours; premium lithium-based extreme pressure grease is recommended with quantitative filling. Keep the bearing surface clean of dust and corrosive medium; regularly check running noise, rotational flexibility and seal integrity, replace timely if abnormal wear or stuck rotation occurs.
For installation, clean matching shaft and seat before assembly, adopt press-fit installation without violent knocking; strictly control shaft alignment error within allowable range, follow standard fastening torque. After installation, conduct no-load test run to ensure smooth rotation, no abnormal vibration and noise, ensuring long-term stable operation of NUTR50110-A INA support roller bearing.
