All machines with rotating elements depend on their bearings for smooth performance, and long and trouble free lifetimes. In heavy duty industries, bearings are subjected to all the conditions most likely to cause their deterioration: vibration, ingress of dirt and contamination, extreme heat and cold to name a few.
Therefore, the quality of the bearings must be matched by the quality of the seals, lubricants and housings to maximise the performance of the system.
As a result SKF has invested heavily in developing bearing systems capable of withstanding the rigours of tough duty cycles. This is particularly true of the bearing housings which are commonly exposed to the harshest environments.
However, no matter how good the bearing is, its performance is dramatically affected if it is fitted poorly or installed in a poor quality housing. SKF's ranges of bearing units and housings have been proven in the broadest cross section of rugged industries.
Some of SKF's most widely used bearing units and housings include:
Y-bearing units
Simple, economic bearing arrangements can be made by using Y-bearing units, which are particularly suitable for applications such as materials handling equipment. The unit consists of a Y-bearing, which is a single row deep groove ball bearing sealed at both sides with a sphered outside curved surface, combined with a housing, typically made from either cast iron, pressed steel or a composite material with a sphered bore.
Y-bearing units are based on proven deep groove ball bearings, with bore tolerances allowing easy mounting on shafts. The units can compensate for initial errors of alignment between shaft and housing of up to
