DBH 1019 radial shaft seal — 105.82 x 139.7 x 14.28

DBH 1019 belongs to radial shaft seal, part of our Seals range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 1019 and any equivalents.

A radial shaft seal like the DBH 1019 keeps lubricant where it belongs and keeps contamination out. It presses into the housing bore and rides on the rotating shaft, so the lip does the sealing work while the case holds the seal in place. With a 105.82 mm shaft, a 139.70 mm housing bore and a 14.28 mm height, this one suits larger shaft equipment running continuously.

Read the code first: 1019 is the designation, and Kz describes the lip and case geometry used in the DBH line. Then confirm the three measurements that decide fit — shaft 105.82 mm, housing bore 139.70 mm, height 14.28 mm. Get any one of them wrong and the seal either will not seat or will not seal, so measure the actual bore and shaft rather than trusting a drawing.

You will typically find this size on gearboxes, pumps, electric motors, rollers and other transmission equipment where the shaft runs above 100 mm. In those spots the seal has two jobs at once: hold oil or grease in, and stop dust, water and particles from getting to the bearing. On process equipment that runs without long stops, replacing the seal on a set interval is normal preventive maintenance.

Before ordering, look at the shaft surface as well. A new lip cannot seal against a groove, scratch or burr, and a worn seat will let the seal spin instead of holding still. If the bore is out of round or damaged, that needs attention too. During installation, coat the lip with lubricant and press the seal in squarely without hammering the edge.

To get a quote on code 1019, send the shaft, housing and height measurements plus the equipment it fits. From there we can cross it within the DBH line or check another brand we supply. If the Kz geometry turns out not to be right for your setup, tell us and we will look at a different lip profile.
