RHP BSB500DUHP4 is an inch-series ball screw support bearing: a single-row angular contact ball bearing with a 60° contact angle, built to carry the high axial loads of a ball screw drive. Bore Diameter: 5.000 in (127 mm). Outside Diameter: 180 mm. Overall Width: 0.875 in (22.23 mm). Contact Angle: 60°. Precision Class: ABEC 7 / P4. Preload: Heavy.
BSB — RHP ball screw support bearing series, 60° contact angle.
500 — inch bore code, 5.000 in (127 mm).
DU — duplex universal: two bearings ground as a matched pair with controlled faces, able to be mounted back-to-back, face-to-face or in tandem.
H — heavy preload.
P4 / EP7 — ISO P4 tolerance, equivalent to ABEC 7.
The 60° contact angle gives high axial stiffness and axial load capacity, the requirement at the fixed end of a ball screw. Heavy preload removes internal play so the screw holds position under reversing thrust. ABEC 7 / P4 tolerances keep runout low for accurate positioning. Rolling Elements: Ball. Number Of Rows: 1. Closure Type: Open. Bore Type: Straight.
Unit Quantity: 2 Pcs. A duplex universal matched pair, carton marked BSB-500-DUH/DFH-EP7.
MPN variants: BSB500DUHP4, BSB500DUHEP7, BSB-500-DUH/DFH-EP7, BSB500DFHEP7, BSB 500 DUH EP7/P4. The carton also carries the marking MM9326WI DUH. The 5.000 in bore is an inch envelope, so metric ball screw support bearings are not direct replacements.
