QCB Thermoplastic Bearing Units

Brand Overview

QCB Thermoplastic Bearing Units provide a lightweight, corrosion-resistant and hygienic alternative to traditional cast iron housed bearings. Manufactured from high-grade glass-filled PBT thermoplastic polyester, these bearing units are designed for applications where cleanliness, chemical resistance and frequent washdown are essential. Unlike coated metal housings, QCB Thermoplastic Bearing Units will not rust, corrode, chip or peel, making them an ideal choice for food processing, pharmaceutical, beverage and chemical industries.

Each housing is fitted with a precision AISI 440 stainless steel bearing insert, stainless steel bolt inserts and grease nipples, and is factory-filled with FDA-approved food-grade grease. The result is a maintenance-friendly bearing unit that offers outstanding durability, excellent dimensional stability and long service life in demanding operating environments.
