10 series Cylindrical roller bearings
The Slimline Solution
When a housing bore or shaft shoulder leaves almost no room for a bearing, the 10 series cylindrical roller bearing is often the only practical answer. For a 50 mm bore, a 1010 bearing is only 16 mm wide compared with 22 mm for a 210 — saving 6 mm of axial space without abandoning the line-contact radial capacity that ball bearings cannot match.
Key Dimensions and Ratings
• Bore range: 20 mm (1004) to 120 mm (1024)
• Width: typically 12-28 mm, versus 14-38 mm for the equivalent 2 series
• Cr range: approximately 8 kN (1004) to 130 kN (1024 E)
• Limiting speed (grease): 8,000-12,000 r/min in small bores; 1,500-2,500 r/min at 100 mm+ bore
• Cages: predominantly machined brass or glass-fibre nylon due to the narrow cross-section
Design Configurations
All four standard configurations are available: N10, NU10, NJ10 and NUP10. Because the 10 series is often selected for precision applications, P5 tolerance is commonly requested alongside C3 radial clearance. The separable rings simplify mounting in cramped housings.
Typical Applications
Printing and paper converting machinery, compact planetary gearboxes, servo and spindle motor shafts, robot joint gearboxes, textile spinning spindles, small pump and compressor assemblies, and medical equipment where weight and envelope are limited.
Ordering and Supply
Specify the complete designation — for example NU1012 M, NUP1014 E, NJ1016 M C3 — together with your application and expected load. P5 precision, special clearance and tapered-bore variants ship within 1-3 weeks. As an ISO 9001-certified Chinese manufacturer exporting worldwide, we support both replacement and OEM programmes.
