Welcome to Linqing Xinshengdi Bearing Co., Ltd.
32312/50 Special Heavy-Duty Tapered Roller Bearing (50mm Bore)
- Dimensions: 50mm Bore x 130mm OD x 48.5mm Width
- Downsizes the standard 60mm bore to 50mm, creating an extra-thick inner ring wall.
- Drastically reduces shaft deflection and eliminates high-stress micro-cracking at the shaft root.
- The ideal severe-duty replacement part for heavy mining equipment and planetary gearsets.
32312/50, 32312-50, 7612/50, Modified 32312 (50x130x48.5mm)
When rotational applications face brutal shock loads, standard bearings risk inner ring fracture. The 35312/50 (commonly logged as 32312/50) modifies standard geometry by dropping the internal bore from 60mm to a heavy-walled 50mm while keeping the massive 130mm OD and 48.5mm width. This creates an incredibly thick inner ring section that absorbs severe dynamic impacts without cracking. It serves as an essential structural solution for heavy-duty earthmoving drives and high-vibration industrial reduction units.
