SKF is launching a new, competitive range of Japanese Industrial Standards (JIS) compliant ball bearing units for the European market that builds on the success of the company’s recently launched JIS-compatible UC offer for Asia. The new UC range is supplied as standard with two types of locking systems, a well proven sealing design and superior machined features, and will be available with full after-sales support through SKF’s global distribution network.
UC bearings offer optimised protection against contaminants and washdown in comparison to similar competitor product offers. The locking mechanisms make the UC range a good choice for material-handling conveyors, where their excellent locking strength and resistance to contaminant ingress ensures a longer, lower maintenance service life. Other prime applications for these bearings include air-handling systems, packaging machines and fitness equipment.
UC ball bearing units offer high levels of protection against contaminants due to a well-proven sealing system, which comprises an integral single-lip inner seal and an external deflector fitted to the inner ring to maximise the sealing function. In addition, the units are designed with a 120 degree angled grub screw locking system for applications that require an even more precise shaft balance at higher speeds, or where vibration may be an issue (the 120deg screw is for bores up to 65mm; larger sizes feature a 62deg screw).
Unlike some competing products, the UC bearing housings feature solid bases and feet to minimise the possibility of contaminant build-up; this is particularly important where cleanliness is an application consideration. Moreover, to comply with prevailing Health & Safety regulations, or to improve protection against the ingress of contaminants in particularly dirty working environments, UC flanged and take-up units can be supplied with optional polypropylene end covers.
A variety of housing styles is offered, including pillow block, short base pillow block, flanged (square, oval or round formats with two-, three- and four-bolt mounting options), and take-up (for linear motion applications). In addition to the UC cylindrical bore with 120deg angled grub screw arrangement (62deg for large bearings), an alternative tapered bore with adapter sleeve is also available in this new series.
