EasyPull jaw pullers TMMA series

Safe and simple dismounting of bearings Equipped with spring- operated arms and safety pin, SKF's new patent-pending EasyPull is one of the most user-friendly and safe tools on the market today. Ergonomically designed, the spring-operated arms enable the user to position the puller behind the component with just one movement of the hand. Costs resulting from exchange of expensive spare parts are avoided with the EasyPull's unique safety pin which breaks instead of the puller itself, should excessive force be used. Additionally, hazardous slipping of the puller claws is avoided due to the special locking mechanism which ensures a tighter grip of the component as the pulling force increases.

User-friendly:

• Extremely user-friendly due to spring operated and self-locking arms, gripping behind the component with just one movement of the hands
• Ergonomic red rings
• Available in three sizes with a maximum withdrawal force of 3, 5 or 8 tonnes (30, 50 or 80 kN), enabling easy selection
• Hydraulic force generators available for the 8 and 5 tonne (80 and 50 kN) versions

Safe:

• The safety pin, or shear pin, is a critical design feature of this product
• The safety pin is designed to break at the maximum load for that puller. Continued breakage of the safety pin may indicate the need for a larger puller
• Safety pin minimises any injury to the user and prevents damage to puller arms, rings and spindle
• Self-locking arms prevent risk of slipping of puller under load

Cost-saving:

• No need to buy expensive spare-parts; a unique safety pin breaks should excessive force be used
• Service life of puller extended by safety pin
• Self-centring avoids damage to shaft
• Efficient use of time due to quick dismounting
