Apart from the standardized GCr15 bearing steel, custom bearings can be made by or combined with a variety of materials or parts, such as M50 and Martensitic.

SV30 stainless steel, L605 cobalt and GR5 titanium alloys, ceramic balls, ceramic rings, special greases or plastics, to meet the most critical application challenges in terms of corrosion resistance, fatigue resistance and wear resistance per customer's application、temperature range and specific technical requirements.

Greetings from MTWB ,a trusted supplier of precision bearings manufactured to international brand standards by 5 leading factories.

Unlike standard bearings, custom bearings (non-standard bearings) are produced per order, allowing flexibility in size, design, material selection, and load optimization. Depending on working conditions, we can implement radial, axial, or radial-shaft combination load schemes to achieve the best performance.

Design & Engineering Advantages

• Optimized raceway grooves on inner and outer rings with larger circular arcs increase ball contact area

• Enhanced internal raceway curvature and ball count can deliver up to 45% longer bearing life compared to standard bearings

• Custom materials include M50, Martensitic SV30 stainless steel, L605 cobalt alloys, GR5 titanium, ceramic balls/rings, special greases, or plastics

• Designed to meet critical application needs for corrosion resistance, wear resistance, and fatigue resistance under specific temperatures and operational conditions

MTWB’s engineering team works closely with customers to understand applications in depth and develop unique bearing solutions before finalizing manufacturing drawings. Currently, we hold 51 active patents in custom bearing technology.
