Heavy Duty Ball Transfer Bearing

The Heavy Duty Ball Transfer Bearing is a semipress fit rolling element designed to move very heavy loads. It is ideal for automated production lines, heavy logistics sorting, and high-load conveying. Available in sizes 12–60, with outer diameters ranging from 18 mm to 100 mm, this unit allows you to transfer heavy stampings, large castings, or pallets with minimal friction. The product ensures smooth operation even under the most demanding conditions.

The main body and adjusting ring are made of S45C carbon steel. For higher specifications, SUS304 stainless steel is also available. The main ball is SUJ2 bearing steel, while secondary balls are made of nylon or POM plastic. The surface can be nickel or chromeplated. Non-stainless steel balls are coated with rust-preventive oil before shipping. Semipress fit installation, combined with tight dimensional control, allows the unit to fit firmly against the mounting surface, reducing vibration and wear.

Each Heavy Duty Ball Transfer Bearing can support 21–800 kg, depending on size. According to international standards, allowable loads range from 20 kg to 1200 kg. The low-friction balls reduce rolling resistance by more than 30% compared with traditional rollers. The S45C steel body provides excellent rigidity. After 100,000 cycles of testing, wear is less than 0.02 mm, meaning significantly less maintenance for your equipment.

Use this bearing wherever heavy parts need to move smoothly – automotive assembly, steel mills, or large-scale distribution centers. Its long service life and low wear keep production lines running with minimal downtime. The Heavy Duty Ball Transfer Bearing is a smart upgrade from plain rollers or wheels.
