Zen Miniature Inch Series Ball Bearings: Common Uses and Applications

Blog | August 27th, 2018

Delivering exceptional performance, Zen miniature inch series ball bearings range in size from a tiny 0.0781-inches to a still diminutive 0.3750-inch inner ring diameter. They’re available with flanged or standard edge profiles, based on the highest engineering standards, and built to satisfy the most challenging operational conditions. Having lauded their attributes, let’s view these ball bearings in action. Let’s check out several common uses and applications for the inch series.

Zen Strengthened Materials 

Structurally tough, the Zen miniature inch series incorporates a surprisingly high strength-to-load rating. Chrome steel delivers strength and hardness, enough to provide ball bearing actuated smoothness to tiny instrumentation shafts. For a stronger material base, the German designers switch to stainless steel, a build that’s harder and more capable, especially in corrosive applications. Used in the shafts of compact food industry equipment, production environment servo motors and more, the inch series adds miniaturized rolling element strength, as employed in an imperial measurements-based setting.

Equipped with Miniature Seals 

When ball bearings are scaled down, the problems experienced by the diminutive friction-negating mechanisms can increase. That truism seems counterintuitive, but there’s a cost to be paid when a smaller device is expected to operate as a high-precision product. In Zen ball bearings, especially the miniature inch series, the tiniest grain of dirt will disrupt the rolling elements so that they skip destructively in their slimline tracks. To stop this undesirable effect, the series incorporates a number of shielding options. Granted, open designs are easier to lubricate, but sealed variants prevent ball-skipping contaminants from entering the sensitive mechanism. Sealing options include the following:

  • Metal seals
  • Rubber shielding
  • PTFE seals
  • Viton seals
  • Non-contact rubber

The sealing mediums are intelligently chosen, according to the contaminant type. For example, PTFE (Polytetrafluoroethylene) is a synthetic fluoropolymer, one that resists corrosive chemicals.

Lubricant-Tuned Performance Characteristics 

Zen Ball bearings, miniaturized and cast as inch series devices, are used in flow control machines, perhaps within a chemical processing plant. They’re installed at the heart of handheld medical instruments, in robotics servo motors, in pharmaceutical production lines, and in countless other essential industrial and commercial usage domains. Their dimensions and material designs are classed as the two most application influencing device attributes, but they’re not solely responsible for a chosen duty. Lubricants, including general-purpose mineral oils with a nathium thickener, further determine frictional coefficients within the compact rolling element architectures.

Progressing further along the lubricant-based designs, there are low-temperature Esters and high-velocity synthetics, each of which has a thickener. Small but packed with engineering know-how, Zen ball bearings, those that occupy the miniature inch series, are precisely engineered so that they exhibit superior rolling element control and strength.
