Detailed Engineering Specifications

Trusted by engineers across multiple sectors, this polycarbonate deep groove ball bearing (31mm ID, 145mm OD, 30mm W) is engineered for superior performance in corrosive and lightweight applications. The inherent chemical inertness of polycarbonate ensures longevity in humid, acidic, or alkaline conditions, while its low density reduces overall system weight. Despite its polymer composition, it maintains excellent load-bearing capabilities for its class, making it suitable for applications requiring moderate radial and axial loads. The precise dimensional tolerances ensure smooth operation and minimal energy loss in power transmission systems.
