Description
EMMAR POLEA 260 3B 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 260 3B and any equivalents.
The EMMAR 260 3B is a V-belt pulley with a 260 mm diameter, three grooves and a section B profile. It transfers power between parallel shafts and lets you set different speed ratios by pairing it with a driving pulley of another diameter. Because MR manufactures this pulley, variants in machining and balancing can be reviewed for your application.
The part number itself carries the specifications: 260 mm diameter, 3 grooves, section B. Section B refers to classic V-belts with a B profile, and the three grooves accept three belts running in parallel to share the load. The 260 mm diameter, together with the diameter of the mating pulley, establishes the transmission ratio of the drive.
Typical installations include compressors, fans, centrifugal pumps, conveyors, mixers and general process equipment, as well as agro-industrial machinery and aggregate processing plants. A three-groove pulley suits medium power requirements and gives a degree of redundancy: if one belt fails, the remaining two continue transmitting until the belt is replaced.
When selecting this pulley, confirm the pitch diameter, belt section, number of grooves and the bushing or bore type. Check that the outside diameter fits the space available and that the driving pulley produces the ratio you need. Align both pulleys carefully at installation to limit uneven wear on belts and bearings, and consider balancing where loads vary.
If you are looking for an equivalent, send the part number 260 3B or simply the diameter and number of grooves required. Pulleys in other sizes, groove counts or sections can be produced, and the bore or bushing can be adapted to your shaft. Include equipment data such as power, RPM, belt type and shaft diameter so the right option can be quoted.

Frequently asked questions
- What does the 260 3B designation indicate?
- It identifies a pulley with a 260 mm diameter, three grooves and a section B profile, which together define its size, the number of belts it accepts and the belt type it takes.
- Is this pulley manufactured by MR?
- Yes. It is manufactured in-house, which allows machining, balancing or groove-count variants to be reviewed against the requirements of the equipment.
- How do I request a pulley in another size or groove count?
- Send the part number 260 3B by WhatsApp or email, or provide the diameter, grooves, section and bore type you need, and a quote for a custom pulley can be prepared.
