INA Catalogue – Radial Insert Ball Bearings and Housing Units

Catalogue SG 1 consolidates radial insert ball bearings and housing units (plummer blocks, flanged and tensioner units). It explains geometries, locking methods (set screws, eccentric locks, adapter sleeves), multi‑lip sealing options and corrosion‑resistant variants for harsh environments. Tabulated data speeds up pairing between insert series and housing styles while highlighting speed limits, tightening torques and seal selection criteria.

Content overview

• Families, sizes and rating tables for quick selection.
• Tolerances, fits and internal clearance/preload.
• Lubrication, sealing and operating limits.

How to use

1. Define loads, speed, temperature and environment.
2. Select the suitable family and verify rating life.
3. Confirm fits, clearances and lubrication plan.

Best practices

• Never transmit mounting loads through rolling elements.
• Ensure alignment; control preload and sealing integrity.
• Monitor vibration/temperature for predictive maintenance.
