Motor Bearings and Bicycle Bearings

A comprehensive range of miniature bearings to utilise in an expansive range of applications

As a leading stockist, we are able to ensure that we stick to strict policies that we have set for ourselves. We always price honestly - costing is always made very clear, we do not ever mislead our clients, which is why we outshine our competitors. Our catalogued is highly detailed because we want our clients to find just the right bearing for the job. Our clients find that the precise detailing on bore size, along with load and speed capability, helps to easily identify the correct items.

Our product range at SMB Bearings is certainly extensive and we currently offer;

316 grade stainless steel bearings - Suitable for shafts between 10mm and 50mm in diameter, these marine grade stainless steel bearings are available with PEEK cages. Bearings are available open or featuring low friction seals and they are manufactured to withstand salt spray, seawater and exposure to a number of different chemicals. What's more, they can also prove temperature resistant, being able to perform effectively in temperatures up to 500 C or 260 C with the PEEK cage. Also suitable for cryogenic facilities where temperatures can fall as low as minus 200 C but this depends on the cage material. The 316 stainless steel cannot be hardened through heat treatments, the stainless steel bearings are only suitable for lower loads and speeds than the 440 grade bearings. In addition, the 316 stainless steel bearings are suitable for use in the food and beverage industry and they can be re-lubricated with suitable food grade lubricants. They are also resistant to corrosion and are available in materials such as ceramic or plastic.

Metric/Inch Ceramic Bearings - Manufactured to fit neatly into shaft sizes from 3mm in size up to 50mm, the ceramic bearings can be provided with rings and balls made from zirconium dioxide or silicon nitride. The silicon nitride and the zirconia bearings can be supplied with or without the cage constructed from PTFE or PEEK. As non conductive and non magnetic, they are corrosion resistant to a number of chemicals, but not suitable for use with hot water or steam. However, they are suitable for use with high temperatures, with the Zirconia can be used up to 400 C whereas the Silicon Nitride suitable for temperatures up to 800 C.

Miniature bearings with extended inner ring - Stainless steel miniature bearings have an inner ring slightly were than the outer ring and are easier to mount with the inner ring removing the requirement for washers or spacers. Several sizes are available in chrome steel but many more are supplied in stainless steel. Furthermore, the extended inner rings are built to withstand heavy loads and moderate movement.

Plastic Bearings - We supply a variety of plastic bearings containing acetal resin rings and nylon cages along with 316 stainless steel or glass balls. The plastic bearings are often used because they will not corrode and they are neither magnetic or conductive, being suitable for a whole range of purposes. In addition, we can also supply a variety of chemical and corrosion resistant plastic bearings constructed from polypropylene or PEEK. Plastic bearings can effectively support low loads and speeds and the acetal bearings are not suitable for use in temperatures above 90C. The PEEK bearings however, can be used at higher temperatures up to 260C.

Popular and Metric Ball Bearings - We have a range of popular and small ball bearings often requested by customers. These varieties are available in shielded, sealed or open and manufactured from chrome steel. As well as this they can withstand heavy radial loads and are available in the EZO range too. Noise sensitive applications can also benefit from the EZO brand or the P6 low noise electric motor grade bearings.

We have a broad range of products available for sale and if there is an item that you require but you don't see it on our website, please contact our team who will be happy to help you to see if we can find the ball bearing that you require.

Below are just some of the applications for SMB products:

  • Automotive Bearings - wiper motor bearings, alternator bearings, steering system bearings etc. The automotive bearings supplied by SMB are built to last and the EZO factory offer bearings for the industry which meet the relevant guidelines and have acquired TS16949 approval, a quality management system which establishes very high standards.
  • Bakery Bearings - bearings for maintenance free performance in temperatures of up to 300C.
  • Bicycle Bearings - bottom bracket bearings and hub bearings. Whether you require bike bearings for road bikes or mountain bikes, we supply a number of different types to suit. The thin section radial ball bearings or cartridge bearings are available with metal shields, contact seals or low friction seals made from rubber. Our EZO range also provides high quality chromium steel or 440 grade stainless steel which offers greater durability. Furthermore, the standard, lubricant in shielded or sealed bearings are resistant to water and include durable lithium grease.
  • Clock Bearings - miniature bearings with a very light instrument oil or completely dry for free movement
  • Corrosion-resistant Bearings- for marine or chemical environments including stainless steel bearings, acetal bearings, polypropylene bearings and ceramic bearings.
  • Domestic Appliance Bearings - for vacuum cleaners, food mixers or washing machines. Finding the right bearings for domestic appliances can prove a challenge as there are so many contaminants. Certain materials can emit vapours, known as out gassing and as such the bearings need to be selected carefully to ensure that they can withstand exposure to the contaminants. Stainless steel as well as ceramics are often the recommended ball bearing materials for vacuum or clean room applications. In addition care should be taken when choosing the bearing lubricant for vacuum or clean rooms as many of the greases can vaporise to an unacceptable level resulting in environmental contamination.
  • Electric Motor Bearings- low noise EMQ grade bearings for noise or vibration critical applications such as hard disk drive motors, servo motors, encoders, vcr capstan motors, vcr drum spindles and polygonal mirror scanner motors.
  • Fishing Reel Bearings - low vibration bearings with oil or grease lubrication for smooth operation.
  • Food Machinery Bearings - stainless steel food grade bearings with approved food greases for motors or food conveyors.
  • Instrument Bearings - oil lubricated or lubricant free instrument bearings for use in small measuring instruments.
  • Medical Equipment Bearings - stainless steel instrument bearings and larger stainless steel bearings for all types of medical equipment.
  • RC Models - for use in radio control cars, slot cars, planes, boats and helicopters as well as model trains.
  • Skate Bearings - precision roller skate bearings, skateboard bearings and in-line skate bearings
  • Vacuum Bearings - dry bearings, moly-disulphide treated or vacuum greased bearings.
