💡 Why use U-groove bearings for track systems?
U-groove bearings are made to roll smoothly along round rails or guide tracks, helping support linear movement with reduced wear and precise alignment - ideal for automation, sliding systems, and 3D printers.

Got the bearings, they are exactly what I needed, they work well and don't see any problems in the future
Great bearings did exactly what I needed them to do, great service!
Good place to do business with.
Don't know where made- I prefer Sweden but we all know the big guys! Tolerance spec'd out and did not seem made of flagrant Chinesium. Put in service and still verking! Sometimes it is just better to get a website that does not need a corporate Purchase order number and RFQ # just for sniffing around. And hell I could not find it anywhere else!
I just cut to the number , qty and buy! I am busy! FFS! also, 5th star comes with 20 years service update...
A potential alternative to the LFR50/5-4NPP bearing with a few caveats. The overall width is actually 10mm (8mm tire width + 2mm inner race width) and the extra 2mm inner race only extends on one side. Thus, a longer axle is required and the U-groove is shifted/offset from the center of the overall bearing width by 2mm. Additionally, the "deep" U-groove measures 5mm wide x 2mm deep (compared to the LFR's 4mm x 1mm) which may or may not be beneficial to your application. In the event someone considers the SG15U before VXB updates the website, I've deducted 1 star just to draw attention to the differences. It is a quality bearing nonetheless.
