UCF 316 offers several advantages that make it suitable for a wide range of industrial applications:
With its robust construction and 80 mm bore diameter, the UCF 316 can support shafts under relatively high radial loads.
The four-bolt square flange housing allows the unit to be mounted securely onto walls, machine frames, and other supporting surfaces. Two set screws on the extended inner ring simplify shaft locking.
The rigid square housing, with overall dimensions of 250 × 250 mm, provides stable support and helps hold the shaft securely during operation.
The insert bearing is sealed on both sides to help prevent dust, particles, and other contaminants from entering while retaining lubricant inside the bearing. Its steel bearing components and durable cast iron housing contribute to reliable operation and a longer service life.
With all these advantages, UCF 316 bearing units are commonly used in the following heavy-duty applications:
The MOQ for the standard UCF 316 with a BKZ logo or no logo is 100 pieces. For OEM orders, the MOQ is 1,000 pieces.
Yes. You can place a trial order without a minimum quantity requirement before placing a bulk order.
Yes. The UC316 insert bearing can be replaced separately if the F316 bearing housing is still in good condition.
Yes. The F316 housing can be purchased separately. Send us the housing model and required quantity to receive a quotation.
Yes. Most UCF 316 bearing units on the market have the same dimensions and operating requirements. Therefore, our UCF 316 can replace branded models with the same specifications and quality requirements.
