The demand for a quiet electric motor – meaning, one that runs with very little noise and vibration – was the primary application that drove engineers to develop and market low-noise ball bearings. Accordingly, the manufacturing equipment industry … [Read more...] about What Are EMQ-Rated Bearings?
A key element of machinery designed for heavy-duty applications, the tapered roller bearing consists of a cone (inner ring), a cup (outer ring), rollers, and a cage. The rollers are tapered in the shape of truncated cones, and both the inner and … [Read more...] about What Are Tapered Roller Bearings?
Steel has long reigned supreme in the bearing world, but thanks to advances in material science, plastic bearings have evolved well beyond the standard injection-molded nylon bearings of times gone by. Polytetrafluoroethylene (PTFE), polyvinylidene … [Read more...] about Are plastic bearings fit for high load applications?
In September 2020, Airbus revealed three concepts for the world’s first zero-emission commercial aircraft which could enter service by 2035. Here, Chris Johnson, managing director of SMB Bearings explains how this grand reveal could spark new life in … [Read more...] about How can bearings contribute to a greener aerospace sector?
By Chris Wilson A good bearing seal plays a key role in many bearings. Bearing seals actively do double duty, preventing contaminants from reaching the inside of your parts while keeping lubricants from leaking out. Both roles can help extend the … [Read more...] about What are the different types of bearing seals?
Sourcing replacement components in pharmaceutical manufacturing While the origin of the first bearing is unknown, Ancient Egyptian drawings depict tree trunks under sleds with liquid-lubricated runners used to move massive stone blocks. While not … [Read more...] about What is bearing obsolescence management?
The temperature of furnaces can reach a whopping 1800° C. For applications exposed to these extremes, how important is choosing and applying the right kind of lubrication? Here, Chris Johnson, managing director of specialist bearings supplier, SMB … [Read more...] about What’s the importance of high-temperature lubricants in bearings?
When most people think of ceramic bearings, they are usually referring to hybrid versions. Hybrid bearings sit in the middle of ceramic and steel, typically including stainless steel races or rings, and ceramic balls. The steel inner and outer rings … [Read more...] about Ceramic bearing: full ceramic or hybrid ceramic?
1. Excessive preload: Excessive preload can have a sharp reduction in life due to increased load on the rollers which in turn increases friction, damages the lubricant and can cause high operating temperatures. 2. Variation between target preload … [Read more...] about What are the potential problems with preload?
The answer to this question would vary on a case-by-case basis and would depend on bearing type, size and operating conditions. For general applications, the operating clearance range should be within the recommended zone shown in the diagram below. … [Read more...] about Preload: How much is too much?
