EMMAR POLEA 170 5B belongs to pulleys, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for POLEA 170 5B and any equivalents.

The 170 5B is a power transmission pulley manufactured in-house under the EMMAR brand. It measures 170 mm in diameter and carries five grooves for section B belts. It transfers motion between parallel shafts in industrial equipment, where speed is increased or reduced and the load is shared across multiple grooves. It mounts on a keyed shaft and is secured with set screws or a taper bushing, depending on the machine.

The code 170 5B packs three pieces of information: the 170 mm outer diameter, the number of grooves (5), and the belt profile it takes, section B. Because EMMAR produces this pulley in-house, the groove machining and balancing are controlled so it runs without vibration at normal belt-drive speeds. The bore is supplied to match your equipment shaft.

Five-groove section B pulleys appear in the power transmissions of compressors, fans, centrifugal pumps, mills, mixers and conveyors. In these machines, the driving or driven pulley accepts several belts to spread the load and limit slippage. The same pulley is also found in agricultural machinery and in plant equipment where a worn pulley is replaced or the transmission ratio is changed.

When selecting and mounting this pulley, check the shaft diameter, the fastening method (keyway, set screw or taper bushing), the center distance and the target transmission ratio. Confirm that the grooves line up with those of the opposing pulley and that belt tension is correct; a misaligned pulley speeds up wear on both the groove and the belt. For equipment running under variable loads, inspect balancing and fastening before start-up.

For an equivalent pulley, send the part number 170 5B or the designation stamped on the machine. You can also supply the diameter, number of grooves, belt section and shaft diameter. With those details, MR Industrial Accessories will quote the pulley that fits your transmission.

To complete your request, send the part number by WhatsApp or email. We will reply with a quote for the 170 5B pulley or the variant you need and explain how to confirm the bore machining and shaft fastening. That helps you avoid ordering a pulley that does not match your equipment.
