Techcon Bronze Bushing, 3/8 in Shaft x 1/2 in (2800-0692)

Description

The Techcon bronze bushing is a sleeve bearing that supports a rotating or sliding shaft inside a Techcon dispensing pump or valve. It bores to a 3/8 inch shaft and measures 1/2 inch long. Bronze runs quiet against steel and carries side load without the shaft cutting into the housing, so the drive stays centered and the dispense volume stays even.

Where the Techcon bronze bushing is used

You find this bushing at shaft supports in benchtop pumps and metering heads that see steady daily cycling. It is a maintenance part because a bearing surface eventually wears and lets the shaft wobble, which shows up as chatter or a drift in shot size. Pressing in a new bushing brings the fit back to spec.

How the Techcon bronze bushing holds up

Bronze holds an oil film well, so the bearing keeps a low, steady friction across long runs. The 3/8 inch bore and 1/2 inch length match the original housing pocket for a press fit without machining. Add a drop of the specified lubricant on install, and check shaft end play after seating to confirm the new bushing has taken up the slack.

Press the bushing in square so the bore stays true to the shaft line. A light chamfer on the housing edge and steady pressure from an arbor press seat it cleanly without cocking. Once it is home, spin the shaft by hand to feel for smooth, even rotation before power goes back on. Because the sleeve is a wear item, pairing the replacement with fresh lubricant and a quick check of the mating shaft for scoring gets the most life out of the new part and keeps shot size repeatable through the next service interval.

Order a spare so a worn bearing never idles a pump mid-shift. Browse related dispensing equipment parts and fittings for shafts and seals, and see the full dispensing line from Techcon Systems.
