🔧 Purpose & Function
The H3134 adapter sleeve is designed to mount tapered bore bearings (e.g., 22234K, 23234K) onto standard cylindrical shafts without the need for complex shaft modifications. The locking system using a nut and washer enables firm axial positioning and resistance to vibration and dynamic loading.
When properly installed, the sleeve ensures concentric alignment between the shaft and bearing, minimizes slippage, and allows for easier removal or repositioning compared to direct shaft mounting.
✅ Common Applications
-
Industrial gearboxes & motors
-
Mining and aggregate crushers
-
Pumps, blowers, and compressors
-
Steel mills and rolling operations
-
Material handling equipment & conveyors
-
Construction & agricultural machinery
This adapter sleeve is widely used in industries where precision, strength, and serviceability are critical under high load and speed conditions.
⚙️ Installation Instructions
-
Clean all mating surfaces (shaft, sleeve, bearing bore) of oil, dirt, and debris.
-
Slide the adapter sleeve onto the shaft to the correct axial location.
-
Position the bearing over the sleeve and push it firmly into place.
-
Screw on the KM34 lock nut and tighten using a hook or impact spanner to the specified torque.
-
Install the MB34 lock washer, bending its tab into a slot to prevent nut rotation.
-
Rotate the shaft manually to ensure smooth movement and verify secure fit before commissioning.
