Revolvo Split Roller Bearings (SRBs), 45 mm

Product Details

Revolvo Split Roller Bearings (SRBs) Fully split to the shaft Housed Cylindrical Roller Bearings with brass cages, perfect for trapped applications, where surrounding equipment would have to be removed (couplings, motors, gearboxes etc.) to fit a normal bearing.Bearing range comparisonRevolvo Split Roller Bearings offer a range of bearing series, providing solutions for a wide range of operating conditions. 01 Light, 02 Medium and 03 Heavy Series accommodate increasingly higher static and dynamic loads.03 Heavy Series Split Roller BearingA more specialised heavy duty series used in the most heavily loaded applications, generally operating at relatively low speed.02 Medium Series Split Roller BearingAn increased section on the 01 Light Series offers additional load-carrying capacity. This series is typically used in arduous, heavily loaded applications where shock loads and vibration may be present.01 Light Series Split Roller BearingThe most commonly supplied series, offering a good combination of load and speed capabilities, with the smallest cross section within the range.Split Roller Bearing TypesRetained Type Bearing (BR)This bearing has integral lips on the outer race, to provide a surface for axial load. The axial load is accommodated on the inner race via the hardened clamp rings, which both align the inner race halves and provide roller guidance. In larger bearings the inner race is manufactured with integral ribs for roller guidance and axial load. This type of bearing will locate the shaft axially as well as providing a means for taking axial load. The retained outer race must be located sideways against one of the housing's grooved shoulders, using the pins and screws provided. Only one retained unit should be mounted on any particular shaft. Additional care should be taken when mounting split roller bearing units on shafts using other, non-split types of bearings (ball, cylindrical, spherical or taper roller etc.) to ensure there are no other locating bearings used. Expansion Type Bearing (BX)This bearing is designed for radial loads only. As in the retained type bearing, the rollers are guided on the inner race by the hardened shoulders of the clamping rings.During expansion or contraction of the shaft rollers are free to move across the plain outer race, offering virtually no resistance to axial movement. Limits for the amount of axial movement are given in the assembly and maintenance section.PLUMMER BLOCK HOUSINGS The compact Split Plummer Block Bearing from Revolvo is the first split cylindrical roller bearing assembly to be interchangeable with standard SNL/SN/SD/SAF series Plummer Blocks - bringing the benefits of a split design to a much wider audience.Complete range of SRB Plummer Block Housing Cast iron Plummer Blocks accommodating adaptor sleeve-mounted solid spherical roller bearings are amongst the most common types in use, supporting rotating shafts in everything from conveyors and fans to line shafts. Yet their replacement is often time-consuming and difficult, due to the need to remove adjacent equipment. Replacing a typical bearing mounted in a cast iron Plummer Block may take anything from hours to several days. In contrast, it may take as few as 1-2 hours to replace an Revolvo split bearing unit.Dimensionally interchangeable with SNL/SN/SD and SAFseries Plummer Blocks. Dramatically reduced downtime for maintenance and replacement. Costs, complexity and time are significantly reduced from that of the standard Plummer Block with solid bearing
