For manufacturers, brands and distributors
Send your drawing or current bearing reference for OEM selection, replacement sourcing or wholesale purchasing. The listed applications include RC models, motors and small rotating mechanisms. For a new application, including a jump-rope handle project, please provide operating requirements for review and sample evaluation before production approval.
Confirm the configuration before ordering
- Required speed, radial and axial loads, running duration and operating temperature.
- Dust, moisture or other environmental exposure, and whether an open bearing suits the assembly.
- Lubrication requirement: state dry, oil or another requested condition for confirmation. Ask us to confirm the supplied lubricant and cage specification for your order.
- Required noise level, radial clearance and inspection method, if these are critical to your application.
- Sample quantity, production quantity, annual demand, packaging or marking requirements and delivery destination.
Speed, noise, service life, compatibility and delivery availability must be confirmed for the selected configuration and operating conditions. A model number alone does not establish these results. Evaluate samples in your actual assembly before approving a production order.
