Bearing pullers Reduce the risk of damaging components and personal injury SKF offers a wide range of bearing pullers for various types of pulls: External, internal and even blind. The range includes mechanical, hydraulic and hydraulically assisted pullers for easy application of high withdrawal forces Bearing puller selection chart Designation Width of grip Effective arm
Bearing fitting tools Mounting bearings in a cold condition Premature bearing failure can result from damage incurred when a bearing is incorrectly mounted Typical problems that can cause premature failures are: Damage caused during the fitting procedure Incorrect sized shafts and housings i.e. too loose or too tight Retaining lock nuts coming loose in operation
Mechanical tools for mounting and dismounting Mounting Small and medium size bearings are generally cold mounted. Traditional methods can cause forces to be transmitted through the rolling elements, resulting in damage to the raceways. SKF’s mechanical mounting tools help prevent bearing damage during cold mounting. Choosing the right puller for the dismounting job is critical.

Hydraulic tool accessories A range of accessories has been developed to further facilitate the ease of use of the SKF hydraulic tools range Hydraulic tool accessories High pressure pipes Flexible solutions to connect oil injection equipment. Maximum working pressure 400 MPa (58 000 psi). Flexible high pressure hoses Maximum working pressure up to 150 MPa
Pressures gauges 100 to 400 MPa (14 500 to 58 000 psi) SKF pressure gauges are designed to fit SKF hydraulic pumps and oil injectors. The gauges are all liquid filled and/or equipped with a restriction screw in order to absorb any sudden pressure drop thereby preventing damage. Safety glass and blowout discs are standard
Hydraulic nuts Easy application of high drive-up forces Mounting bearings on tapered seatings can be a difficult and time-consuming job. Using an SKF Hydraulic Nut facilitates easy and quick application of the high drive-up forces required for mounting bearings. Dismounting bearings mounted on either adapter or withdrawal sleeves is also often a difficult and time-consuming

Hydraulic tools for mounting and dismounting SKF has pioneered the use of hydraulic techniques, which have helped to simplify bearing arrangements and facilitate correct and easy mounting. SKF has also developed a comprehensive range of tools and equipment to put these hydraulic techniques into effect. The SKF hydraulic techniques are often the preferred method for
Maintenance products Help your bearing achieve its maximum service life Every bearing has a certain service life potential. However, research has shown that, for various reasons, not every bearing achieves it. Important stages which have a major impact on a bearing service life can be recognised during the bearing’s lifecycle. These stages are mounting, lubrication,
