Dust-Resistant Bearings

Overview

DGBB

NMT's dust-resistant bearings use a special material with a polyolefin resin that has an affinity for lubrication oil. This unique material is sealed in the bearing and provides continuous lubrication in tough environments with dust, wood chips, or other contaminants.

Stainless steel options are available for environments where bearings are also exposed to water.


Product List

Single-Row Deep Groove Ball Bearings

Molded-Oil™ bearings feature a special material that provides a continuous supply of lubricating oil, allowing them to stand up to dust-contaminated environments at atmospheric pressure.

Features

  • Long life
    A specialized material provides constant lubrication that extends operating life.
  • Maintenance free
    Eliminating the need for relubrication, Molded-Oil bearings provide a cleaner environment with longer life than grease-lubricated bearings.

Applications

  • Agricultural machinery
  • Woodworking machinery

FAQs

answers Loads are defined by their direction. Loads perpendicular to the shaft are called radial loads and loads parallel to the shaft are called axial (thrust) loads.

 

answers While DGBBs can handle axial loads in both directions, single-row angular contact ball bearings can only receive axial load in one direction.

 

answers Seals and shields offer additional protection for bearing components and help to improve and maintain lubrication. In terms of sealing performance, sealed bearings rank best, followed by shielded bearings, then finally open bearings.
NMT uses supplementary designations D, DU, DW, and V (DD, DDU, DDW, VV) for sealed bearings and Z (ZZ) for shielded bearings. No supplementary designations are listed for open bearings.
