For simplicity’s sake, let’s look at how a plain bearing works. Check out our GLRSW Stainless Steel Series K Spherical Plain Bearings for a good example. You have an inner ring and an outer ring, between which may be sandwiched a set of balls, pins or rollers, which are lubricated (the GLRSW uses chrome plated steel ball bearings). One of the rings is fixed, and the other is free to rotate. Some sort of clamping or pressure fit will be used to affix the stationery ring.
The material used for a bearing is key. For its inner ring, our GLRSW uses a special high-strength bronze (CuSn8) with a PTFE liner.
Proper and stable mounting of the bearing are also essential to good performance. Looseness will result in vibration and noise, shock loads relative to speed, and eventually the actual destruction of the bearing and adjacent parts. Meanwhile, seeing as friction always creates heat, wear and tear, lubrication is an essential part of a bearing. Otherwise, once again bearing destruction is the result. The bearings shown on this page have PTFE liners which make them self-lubricating and maintenance-free.
You’ll need to use your engineering expertise when calculating the appropriate bearing for your application, taking into account things like static and dynamic load ratings and limiting speed. Fortunately the bearings we offer have all this information included in the dimensional tables, and you can always consult with our Technical Sales Associates for any additional information you need about our components; just call us at 800-877-8351.
