Description
NSK BSS5050-2EG belongs to ball screw, part of our Linear motion range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for BSS5050-2EG and any equivalents.
The NSK BSS series ball screw turns rotary input into axial movement with high efficiency and positioning accuracy. It suits machine tools, automation equipment and any system where repeatability matters. MR Industrial Accessories supplies this series to customers across the United States and in several Latin American countries, and can help you match a model to your application.
The designation is built in blocks. Letters come first and identify the family; the digits after them give nominal diameter and lead. Take BSS1215-2EG: shaft 12, lead 15, and the -2EG suffix covering circuit count and return type. In BSS2510-4EG the shaft is 25, the lead 10 and the circuits 4. Reading the code this way lets you order the exact screw.
Typical installations include machining centers, CNC milling machines, grinding machines, Cartesian robots and measuring equipment, as well as precision presses and automated conveying systems. Low friction plus the ability to carry axial and radial loads makes these screws suitable for fast, demanding cycles.
When selecting a BSS ball screw, review the axial load, rotation speed, required precision and the working environment. The EG seal keeps contaminants out and lubricant in. Alignment between screw, guide and nut has to be correct, and suitable supports must be used. Lubrication on schedule and controlled axial play are what preserve repeatability over time.
Interchange with other brands using similar diameter and lead standards is possible, but mounting dimensions, thread and nut type must be checked first. If you only have another maker's number or an unidentified part, send us the data and we will identify the equivalent. We work from the exact designation on your drawings.

Frequently asked questions
- What does the EG suffix mean on BSS ball screws?
- EG refers to the seal and ball return type. In this series it is tied to an external return design with protection against contaminants. Send the complete part number and we will confirm the exact configuration of your model.
- How do I choose the right diameter and lead for my application?
- Diameter and lead follow from axial load, speed and the precision you need. A larger lead travels further per revolution but resolves less. Describe the motion required and we will help you pick the right BSS model.
- Can you help if I only have another brand's part number?
- Yes. Send us the data or the unidentified part and we will tell you the compatible equivalent, after verifying mounting dimensions, thread and nut type.
