Different types of Ball Transfer Units

Omnitrack ball transfer units (BTU) are an advanced type of bearing engineered to allow precision omnidirectional movement or conveying of heavy items.

Omnitrack units vary:

  • Construction – Pressed (stamped) steel construction, or components machined from solid steel or plastic materials.
  • Range – Light and medium duty use the simple cup and ball ‘hemispherical recirculation chamber system whereas heavy duty ranges use the ‘endless track’ or full race recirculation system.
  • Main ball size – From 12.7mm (0.5”) to 101.6mm (4”)
  • Load carrying capacity, from 15kg (35lbs) to 8000kg (18000lbs) each.
  • Materials – Chrome steel, stainless steel, Delrin (Acetal / POM)

The heavy-duty range does not normally require user servicing as they are lubricated for life and produced using the patented Omnitrack endless track design. We have come across applications where the units have been subjected in error to, for example, excessive shock loads or ingress of slurry or contaminants which has necessitated the dismantling of the unit for user servicing. In these situations, having a service kit ready on the shelf can restore the function and efficiency of the ball unit within your application in minutes!

User servicing and service kits: Can I service my ball transfer units?

Omnitrack 9000 series heavy duty ball transfer units are user-serviceable. This range used to be called the high capacity range. Compact 8000 series heavy-duty range ball transfers incorporate the ‘endless track’ or ‘full recirculation’ design. But due to their miniature size are unsuitable for user servicing.

Spring-loaded ball units from our 94 series can be reconditioned. 95, 96 and 97 series require the use of a press and special tooling to safely dismantle the ball transfer, so we recommend factory reconditioning in this case.

Ball Transfer Units Servicing

For overhaul instructions to maintain your ball transfer unit we have a video clip which guides you through the strip down, cleaning and reassembly process.

Ball transfer unit servicing requires a kit of spare parts. You can buy 2 types of service kit ‘S1’ and ‘S2’ depending on extensive you want to refurbish the ball unit. See the list of spare part components below which show which spares are included in S1 and S2 service kits.

  1. Circlip (S2)
  2. Felt seal (S1 & S2)
  3. Main ball (S1 & S2)
  4. Recirculating balls (S1 & S2)
  5. Retainer (S2)
  6. Table (S2)

To order, provide us with the original part number, any identification mark and the service kit you require (e.g. S1- [part number]). If there’s no visible part number or marking, simply send us a sketch or photo of the unit we’ll identify it from our records.

Contact us directly for advice — we’re happy to point you in the direction of the service kit you need!

Factory Reconditioning Service

Multiple fixing and spring preload variations of Omnitrack ball transfer units can usually be restored to the original performance by using our factory reconditioning service which is also available for most heavy load and custom units.

Spring-loaded ball transfers are usually prestressed to limit spring depression until a theoretical load is exceeded. Due to the preloaded state of the disc or coil springs, we use special tooling to disassemble these units safely. We’ve over 75 years of production drawings and spring configurations for all Omnitrack ball transfer units produced.  

Precision Engineers since 1909 – Original manufacturers & inventors of heavy-duty Ball Units since 1954.
