Self Aligning Spherical Roller Bearing With Tapered Bore For Heavy Loads 45 mm ID 100 mm OD 25 mm Width C3 Clearance NSK Bearing For Misalignment Compensation And Long Life In Harsh Environments

Single NSK 21309 Spherical Roller Bearing with bore 1:12
✔️ ID 45 mm, OD 100 mm, width 25 mm, bore 1:12, C3 clearance

Engineered by NSK, the 21309 EAKE4C3 spherical roller bearing handles heavy radial and axial loads with a tapered bore for simple mounting. Its self-aligning feature accommodates shaft misalignment and deflections, keeping friction and heat low in conveyors, mills, and heavy equipment. EAKE4C3 clearance supports thermal expansion and steady performance in tough environments.

✅ Inside diameter 45 mm, outer diameter 100 mm, width 25 mm
✅ Tapered bore 1:12 with EAKE4C3 clearance
✅ Self-aligning design with robust steel cage for durability
✅ Suitable for high-load, bidirectional operation in industrial gear

💡 What is a spherical roller bearing with tapered bore used for?

This handy, high-capacity bearing is used across heavy machinery to handle loads and keep shafts aligned. - heavy-duty radial and axial load support for conveyors, mills, and gearboxes - self-aligning action tolerates shaft misalignment and deflection - tapered bore 1:12 for easy mounting on standard shafts - EAKE4C3 clearance and steel cage ensure durability and steady performance
