Pillow Block Bearing — ¾″ Bronze Sleeve Insert - NWOV and Others

This bearing is designed for ACME screw support in wheelchair lifts (e.g. lower nut bearing in National Wheel‑O‑Vator CDE42 units) and replaces legacy #V1337.

This pillow block bearing provides reliable support under thrust and radial load, with a bronze sleeve insert that runs cooler and wears longer. Its pressed steel housing and replaceable rubber grommets reduce noise and vibration. It’s suitable for vertical or horizontal mounting and includes an oil cap for maintenance.

Please ensure installation is carried out only by qualified technicians. Proper alignment, torque, and lubrication are essential to maintain safety and extend service life.
