Self Aligning Ball Bearings work in a similar way to standard ball bearings but feature two rows of balls which help with alignment by rotating in parallel with the outer ring. The inner ring features two raceways and the outer ring has one raceway. Thrust Ball Bearings The .177, as we mentioned earlier, is used by professional bodies (including Olympic events) for international 10-meter shooting. The truth is that .177 airguns (well, target airguns) are more accurate at this particular range. Much longer than this though their accuracy will drop-off due to them being lighter. To identify your bearing requirements more precisely, it helps to have the following information to hand: When it comes to handling radial and thrust loads of small applications, Ball Bearings are the most common mechanical elements that are used. Ball Bearings are best used to reduce rotational friction when supporting loads. Bearing Shop UK provides a number of sealed, shielded or open type Ball Bearings. Steel balls like this are made primarily from impacted lengths of wire, then ground to a spherical shape. The balls are hardened and tempered through their whole diameter in an electric furnace. Grade 100 Chrome Steel, when formed this way, has a sphericity of 0.0025mm and a hardness of HRC 60-67.

If you’re new to the sport then this isn’t really relevant at all, only if you’ve been using airguns for years and find the .177 and .22 just aren’t fit for your purpose will you start looking at higher caliber ammunition. Actually, for around three-quarters of a century, the .22 caliber was by far the most popular pellet in the US. It was only around 40 or 50 years ago when airguns from Great Britain and the rest of Europe (who used the .177 primarily) started becoming popular in the US that this caliber overtook the .22 in usage. There are some good reasons why the .177 is the most popular. There are more different types of pellets you can use for airguns that accommodate the .177, you’ve just got far more choice. Also, the pellets are cheaper than the .22 and you get more of them in a tin. In fact, the price difference tends to work out between 25-35%, it makes a difference. Except for "S", all bearings are made from ball bearing chrome steel. All "S" prefix bearings are stainless steel. The truth is, no caliber is inherently more accurate than the other. It depends on the environment where you’re shooting.It is a good question though and for a long time (about 30 years if I’m honest!) I personally thought the .22 was the most accurate. I never really questioned why I thought this though. mm) – for a long time, several decades, in fact, this was the largest caliber available for airguns.

Ball Bearing TypesThe most commonly used pellet, the .177 caliber pellet is not only a great round for casual shooting and training but is also used for professional target shooting up to a range of around 10 meters and is also used at Olympic events. Most bearings, especially for industrial applications follow an internationally recognised bearing identification system. In some cases, the bearing will have a prefix, followed by a group of numbers, followed by a suffix. Some of the common prefixes and suffixes are mentioned below: Prefix
