Bearing Unit Assembly
Crystals Group is a manufacturer and supplier of Bearing Unit Assemblies for shot blasting machine applications. The range includes Shot Blasting Bearing Units, Wheel Bearing Units, Bearing Housings and RLM 195 Bearing Units, manufactured according to the requirements of the applicable equipment.
What is a Bearing Unit Assembly?
A Bearing Unit Assembly is a mechanical assembly used to support and accommodate the bearing arrangement within a shot blasting machine. It forms part of the wheel assembly and is designed to maintain the required positioning and operation of the rotating components.
Crystals Group manufactures Bearing Unit Assemblies and related bearing components according to the required size and machine configuration.
Why is a Bearing Unit Assembly Important?
The Bearing Unit Assembly supports the rotating components of the shot blasting wheel and requires accurate fitment for proper operation. The bearing housing and bearing seat are important parts of the assembly, as any off-centre condition can affect the alignment of the bearing arrangement.
Crystals Group manufactures bearing housings using horizontal boring machines to help maintain accuracy in the bearing seat.
Bearing Unit Assembly for Shot Blasting Machines
Crystals Group supplies Bearing Unit Assemblies for different shot blasting machine requirements. The product range includes standard Bearing Unit Assemblies, Shot Blasting Bearing Units, Wheel Bearing Units and RLM 195 Bearing Units.
The appropriate bearing unit depends on the machine design, required dimensions and wheel assembly configuration. Customers can provide their existing bearing unit or machine details to identify the applicable requirement.
Manufacturing of Bearing Unit Assemblies
Crystals Group manufactures the shafts used in the assemblies from EN-8 or EN-36 grade material. The shafts are hardened and tempered to 32–35 HRC and then ground according to the required size.
The bearing housings are manufactured using a horizontal boring machine to help avoid off-centre conditions in the bearing seat. The assemblies use genuine bearings, including bearings from SKF, NTN and Hyatt, according to the product requirements.
Testing of Bearing Unit Assemblies
Crystals Group follows an assembly testing process before dispatch. The assembly is initially run at different intervals of 5, 10 and 15 minutes at low RPM, after which the RPM is gradually increased to synchronise the complete assembly.
During the trial run, the temperature of the housing is continuously monitored and changes in amperage are also taken into account. The Bearing Unit Assembly is dispatched after the required amperage and temperature range is achieved.
