The two photos show a flange-mounted linear bearing nut designed to run on round shafts in conjunction with a ball screw assembly. Front and side angles are both shown, which gives a clear picture of what this component actually looks like in hand before it goes into a machine.
The snap ring groove visible on the outer body is the detail worth paying attention to. In a standard linear bearing, securing the component inside its housing relies entirely on the fit tolerance between the bearing outer diameter and the bore it sits in. That works fine in many applications, but in vertical installations or anywhere the bearing might be subjected to axial shock loads, a snap ring gives you a positive mechanical stop that the interference fit alone cannot provide. The bearing stays located even when the load direction reverses or vibration works at the joint over time. We offer customizable snap ring configurations on this product, so customers working with non-standard housing dimensions or specific retention requirements can get a setup that actually fits their design rather than adapting around a catalog standard.
The flange itself is a practical feature that tends to get overlooked when buyers are focused on shaft size and load ratings. A flanged bearing nut bolts directly to a face plate or carriage end, which means no housing bore needs to be machined into the structure - the mounting is external and the bolt pattern does the positioning work. That cuts machining time on the customer's end and makes replacement straightforward later on. The four-bolt rectangular flange pattern in these photos is a widely used layout that fits standard carriage plate designs without modification.
Paired with a ball screw, this type of bearing nut handles the rotational constraint on the shaft - the ball screw drives linear movement while the bearing nut and its housing keep the shaft from rotating and guide it axially. Getting that pairing right matters for both positioning accuracy and how evenly the bearing wears over its service life.
