In conjunction with the Best by Design awards, we invite you to cast your vote for the Motion Medalist awards. Presented here are components featured over the last year of Motion System Design — products that span motion control and power transmission design. Simply go to motionsystemdesign.com/bestbydesign (or email us at msdeditor@penton.com) to rank these products by how useful you think they are. Top-rated products will be announced this spring.

Retaining rings take up less space

Hoopster retaining rings fit into much shallower grooves than regular snap rings or retaining rings, and are suitable for light to heavy loads.

  • For thin-wall tubes; low profile, precision circularity, small radial size, high thrust capacity

  • Will not twist or deform under load as do conventional retaining rings

  • Controller is programmable

    Carbon and 302 stainless steel in sizes from 3/8 to 3 in.
