Hope Bearing - 61902 2RS

This is the bearing's size and type designation. '61902' refers to the specific internal and external dimensions (bore and diameter), and '2RS' indicates it has rubber seals on both sides for enhanced protection against contaminants.

While it might be possible if the dimensions are identical, using a genuine Hope bearing is recommended to ensure compatibility, quality, and the intended performance of your Hope hub.

Lifespan varies greatly depending on riding conditions, maintenance, and installation. Under typical use, a properly installed and cared-for bearing can last several seasons. Rough conditions or poor installation can significantly shorten its life.

No, the bearing comes pre-greased and sealed. Attempting to add more grease or breaking the seals can introduce contaminants and may void any implicit warranty.

Essential tools include a bearing press kit, possibly a vice, and a soft-faced hammer or mallet for lightly tapping components if necessary. A bearing puller may also be required for removal.

Check the official Hope Technology website for technical manuals or diagrams related to your specific hub model. If unsure, contacting Hope's customer support is recommended.

Ensure the bearing was pressed in perfectly square and not cocked. Re-check for any obstructions or damage to the hub shell or bearing seat. Verify the correct bearing size was used.

Check if the bearing was installed correctly without being forced. Assess riding conditions; excessive exposure to water or grit can reduce bearing life despite seals. Ensure the hub's freehub or other components are not causing undue stress on the bearing.

Use an appropriate bearing puller tool designed for hubs. Apply steady, even pressure. If seized, a penetrating lubricant may help, but care must be taken not to damage the hub shell. Professional assistance may be required.
