Power Transmission
clamps the two cage halves together. These are prone to falling out during assembly and inspection processes, and can easily be lost which can halt production, greatly reducing the benefits of the SRB design. To remedy this problem, Revolvo
developed an integrated retained cage clip design. The integrated cage clip is firmly attached to one half of the cage via spiral pins and can easily be clipped onto the other half during assembly – and removed with a flathead screwdriver during disassembly – with no risk of loss. This design also speeds up the installation process by effectively allowing the engineer a ‘free-hand’. The benefits of reduced installation and maintenance costs of SRB design are only relevant as long as the bearings offer similar performance (or better) in terms of reliability when compared to standard roller bearings. If a bearing is unable to survive in an industrial application then it will never deliver improved efficiency and cost savings. The housing and support pedestal design must be able to cope with the
mechanical stresses which will be applied in the application as well as any additional environmental hazards, such as corrosive material, submersion in water or extreme temperatures. Finding an SRB split bearing support pedestal that is manufactured from robust cast iron (HT250- grade material to BSEN1561, 1997, for example) maximises durability; though the actual design of the casting also has an influence, and Revolvo has optimised its design of support pedestal cap by incorporating stiffening ribs to significantly increase rigidity.

anufacturers have a responsibility to the customer to offer the best available design, technology and materials across its entire range and without a cost penalty.
Despite the undeniable benefits that split roller bearings bring to industrial applications there are many site managers that are wary of specifying them in place of standard roller bearings
