HEPCO BALL SCREW hepcomotion.com HepcoMotion.com

Hepco ball screw offers a competitively priced range of Precision Rolled ball screws, Nuts and Bearings Housings. Supply options HBSS Series HBSM Series Ball screw and Nut Types The HBSS series is a single nut DIN 69051 flange design, available in two accuracy grades (C5 and C7) with controlled play (A0) and no play (A1) nuts. For preload critical applications, the C5 grade ball screw can be supplied with a lightly preloaded nut (A2). Complementing the range, are high lead screws (HBSH series) and miniature screws (HBSM series). For a complete list of the accuracy and preload combinations, please...

Ball screw and Nut Types Availability of Preload Grade Type Accuracy Grade Light preload (maximum lead deviation of 0.018mm per 300mm of travel) (maximum lead deviation of 0.018mm per 300mm of travel) Part Number Supply Options Ball screw units will be supplied with the ends machined and the nut assembled onto the screw. Disassembly of the nut from the screw is not possible without the aid of a special mandrel, in order to prevent the loss of the recirculating balls. We recommend that units are purchased with the ends ready machined to one of the standard configurations, outlined in this catalogue,...

HBSH Series - High Lead Screws HepcoMotion HBSH ball screws are generally suited to applications that demand linear velocities above 0.5m/s. Please refer to & 10 for more information on maximum speeds. The series includes a range of screw diameters from Ø16mm to Ø50mm, and is available in C5 or C7 rolled accuracy grades*1,2. HBSM Series - Miniature Series HepcoMotion HBSM ball screws offer high positional resolution and a compact design*1. The series includes a range of screw diameters from Ø6mm to Ø14mm, and is available in the C7 rolled accuracy grade, as standard*2,3. C Load Capacity (kN)...

BHF Bearing Housing - Fixed End BEK Bearing Housing - Fixed End HepcoMotion BHF bearing housings are suitable for DIN 69051 standard and high lead ball screws. The housings are made from chemically blackened steel and contain a pair of matched angular contact bearings, to provide accurate radial and axial location for the ball screw. HepcoMotion BEK bearing housings are suitable for miniature ball screws. The housings are made from chemically blackened steel and contain a pair of matched angular contact bearings, to provide accurate radial and axial location for the ball screw. On installation,...

BEF & BHS Bearing Housings - Supported End HepcoMotion BEF and BHS bearing housings are made from chemically blackened steel and have an accurately machined bore, into which a deep groove ball bearing is fitted. The bearing is a sliding fit in the bore and is axially located onto the end of the ball screw using a circlip, which is included with the unit. Standard machined ‘Support Ends’ fit into these housings (see Figure B on & 9). BEF 8 — BEF 1214 Shaft End Machining Details An optional keyway can be machined to suit DIN6885 parallel keys*2. Hepco can machine ends to custom requirements, on...

Technical Information and Calculations Rotational Speed Buckling Load The speed of a ball screw is generally specified in terms of its linear velocity. The rotational speed is calculated using the following equation: n = rotational speed (rpm) v n = x 103 v = linear velocity (m/min) P P = pitch (mm) The graph below shows the maximum axial compressive load which would cause the ball screw to bend or buckle. This maximum load depends on the diameter of the ball screw, the method of end fixing and free length L. The four scales correspond to the four mounting options. The chart includes a safety...

Technical Information and Calculations Average Speed and Average Load Where the speed varies through the machine cycle, average speed is calculated as follows: nm = average speed (rpm) q = time fraction (%) Where the load and speed varies, the effective load is calculated as follows: Accuracy grade (C...) preload (A...) combination Standard options: C5 A2*, C7 A1*, or C7 A0 * Option is not available as standard on HBSM type.
