TT742 8-15mm Blind Hole Bearing Puller Split Collet Extractor Kit
TT742 8-15mm Blind Hole Bearing Puller Split Collet Extractor Kit
Description
π§ Product Overview
Unbranded blind-hole bearing puller kit designed for removing small bearings, bushes and similar components seated in recessed or blind housings where conventional external puller jaws cannot reach behind the component.
The kit uses an expanding split-collet system. The correctly sized collet is inserted through the centre of the bearing, then expanded behind or inside the bearing by tightening its locking section. The supplied beam-and-leg puller assembly is then attached so the central forcing screw can withdraw the bearing from its housing in a controlled, straight movement.
β Key Features
β’ Blind-hole internal bearing extraction system
β’ Four interchangeable split collets
β’ Confirmed collet diameters: 8mm, 10mm, 12mm and 15mm
β’ Beam-and-leg puller assembly with central forcing screw
β’ Expanding collets grip the internal surface of the bearing
β’ Designed for applications with restricted rear access
β’ Mechanical screw-operated extraction
β’ Fitted storage case with moulded insert
β’ Unbranded tool set
π© Operating Method
- Select the split collet matching the internal diameter of the bearing or bush.
- Insert the collet through the centre of the component.
- Tighten the collet so its split end expands and grips securely.
- Connect the beam-and-leg puller assembly to the collet.
- Position the puller legs securely against the surrounding housing surface.
- Turn the central forcing screw gradually to draw the bearing or bush from its bore.
The collet must be correctly sized and securely expanded before extraction begins. The puller should remain centred to reduce the risk of uneven loading or damage to the component housing.
π Collet Sizes
β’ 8mm
β’ 10mm
β’ 12mm
β’ 15mm
These measurements describe the stated collet diameters. The exact usable range may depend on how far each collet can safely expand.
π οΈ Typical Applications
Suitable for extracting compatible small internal components such as:
β’ Blind-hole bearings
β’ Pilot bearings
β’ Bearing races
β’ Internal bushes
β’ Sleeves and similar recessed components
Suitability depends on the componentβs internal diameter, available gripping surface and surrounding clearance.
