The SKF TMBS is a jaw-type hydraulic puller with an integrated cylinder, built for dismounting bearings, pulleys, gears and other interference-fit parts. Hydraulic force does the heavy lifting, so jobs that would demand extreme torque or risky blows with a mechanical puller can be handled in a controlled way. MR Industrial Accessories supplies this line and helps you match the model to the job.

In the TMBS code, the letters identify SKF's family of hydraulic jaw pullers. The figure that follows, as in TMBS 50-4A, relates to the size or capacity of the tool, while the trailing letter and hyphen point to a configuration variant such as jaw count, cylinder style or spread range. Rather than guessing at a code, send the full designation and we will confirm the model and whether it fits your application.

You will find these pullers in maintenance shops, industrial plants, mining, cement, paper mills and service companies. Typical work includes tearing down gearboxes, pumps, electric motors and other rotating equipment where bearings sit on an interference fit. Food processing, oil, steel and power generation operations also use them to cut downtime and protect shafts and housings from damage.

Selecting a model comes down to three things: the outside diameter of the part being removed, how deep the jaws need to reach, and the clearance around the component. Jaws should bear on a solid surface, never on cages or seals. Keep the cylinder aligned with the shaft, since an off-center load can bend the spindle or ruin the part. Before pressurizing, confirm the ram is centered and the jaws are seated evenly. Thread lubrication and proper cylinder bleeding also influence how the tool performs.

Hydraulic pullers from different makers are not necessarily interchangeable. Clamping mechanisms, cylinder stroke and supplied accessories can vary, so matching nominal capacity alone is not enough. Check jaw compatibility and the hydraulic connection type as well. If you are unsure, send the part number of the component to be pulled along with your working space, and MR Industrial Accessories will help you pick the right tool.
