What Are Non-Standard Spherical Roller Bearings?
Non-standard spherical roller bearings are custom-designed bearing solutions that cannot be replaced by standard series such as 222, 223, 230 or 240 series. They are engineered based on specific equipment requirements, drawings, or extreme working conditions.
Compared with standard bearings, non-standard designs allow full flexibility in dimensions, internal structure, clearance, cage type, and material selection, making them ideal for large-scale industrial machinery where standard solutions fail.
Key Custom Parameters
Non-standard spherical roller bearings are fully customizable based on application requirements and engineering drawings. Below are the key technical parameters available for customization:
Inner Diameter
100mm – 1500mm (custom sizes available)
Tapered Bore
Cylindrical bore / Tapered bore (1:12, 1:30, or custom taper)
Cage Types
Brass, steel, or polymer cages optimized for heavy load, vibration, and high temperature
Internal Clearance Default C3
C2 / C3 (standard for heavy duty) / C4 / C5 for extreme conditions
Precision Class Default P0
P0 / P6 / P5 / P4 available upon request
Other Custom Options
Materials, sealing, lubrication and anti-corrosion solutions for harsh conditions.
