LDK ACCU-GRIP® Concentric Locking Insert Bearings Information


Concentric Locking Insert Bearings


LDK's Accu-Grip(R)for quieter,smoother,more efficient running bearings under higher radial  loads and rotating speeds.


  • Ture Shaft Centering

The inner race closes down on the shaft from all sides creating a true shaft centering resulting in even and constant balance.


  • Concentric Locking

Provides uniform grip of the inner race to the shaft at the leading edge of the locking collar,resulting in lower noise and vibration at higher speeds.


  • Quick and Easy Installation

Installs in seconds-only one cap screw tighten down,in one position.


  • Shaft Protection

The concentric locking force significantly reduces the chance of marring or damaging the shaft. Thus significantly reduce fretting corrosion on shaft.For stainless steel Accu-Grip series, due to this feature, it will significantly reduce bacteria and thus it's a better choice for food processing industry which requires high hygeian requirement.


  • More Efficient Fan Balancing

Because the Accu-Grip ball bearing is totally concentric with the shaft,it will not induce vibration into the fan/blower system and will reduce the fan OEM's trim balancing time for high speed applications. No 1 choice for HVAC industry.


  • Reduced Shaft Costs

The Accu-Grip ball bearing only requires commercial grade shafting tolerances.This can save approximately 40%in shafting costs versus turned,ground and polished shafting. Available in metric &inch and could be used with any standard duty housing style(cast iron,stainless steel and thermoplastic).A drop in replacement for AMI- Accu-Loc(R) and SealMaster-Skwezloc(R)
