Customer Reviews for 2 Set SBR20-1200mm 20mm Fully Supported Linear Rail Shaft Rod With 4 SBR20UU + SBR16-2000mm Linear Slide Guide 16mm Shaft 2 Rail With 4SBR16UU Bearing Block CNC
48 inches, straight, no binding. Bearing blocks have smooth motion. Glad i bought 3 sets. No trouble with any of them. 4 stars because i have never rated anything 5 out of 5. These are beefy and worth the price to me.
the product quality is as I expected. The linear bearing are much better than the standard ones in term of quality. The seller speeded up my purchase and I got it on time. I recommend this item.
