V-belt pulley SPB 450-4 - TL. 3535

V-belt pulley SPB 450-4 - TL. 3535 – pulley for V-belt drive

V-belt pulley SPB 450-4 - TL. 3535 is an SPB V-belt pulley for taper-lock mounting, intended for belt drives where a V-belt must transfer power between two shafts. The pulley is made of cast iron and is relevant when you need a stable V-belt pulley for industrial belt drives, machine service or replacing an existing pulley.

The SPB profile is often chosen for more powerful belt drives, where the pulley must work together with wider V-belts and transmit more power.

What is this V-belt pulley used for?

With 4 grooves, the pulley is suitable for multi-groove belt drives, where the load is distributed over several V-belts. Typical applications are industrial machines, engine installations, ventilation systems, pu and equipment where a stable V-belt drive is required. A V-belt pulley is also called a pulley, V-belt pulley or belt pulley, and the right combination of belt and pulley is essential for smooth operation and good power transmission.

Advantages of taper-lock mounting

Taper-lock mounting makes it easier to mount the pulley firmly and centrally on the shaft with a suitable taper-lock bushing. On this product, the taper-lock type is specified as TL. 3535, and must therefore be matched to the correct bushing and shaft diameter in the specific machine. The advantage of taper-lock is that the pulley can usually be mounted and dismounted more conveniently than a traditional fixed hub pulley, while the solution provides a secure mechanical connection when mounted correctly.

Technical characteristics

• Profile: SPB
• Diameter: 450mm
• Outer diameter (Da): 457mm
• Effective diameter (Dw): 450mm
• Number of grooves: 4
• Taper lock: TL. 3535
• Material: Cast iron
• Suitable for: V-belt drive with SPB profile
• Crown width (b2): 82mm
• Drawing type: 8

The technical data makes it easier to compare the pulley with the part already installed in the machine. In particular, the profile, diameter, number of grooves and taper-lock type should be checked before ordering the item.

How to choose the right pulley

When choosing a pulley for a V-belt, it is important to check that the belt profile matches the belt. This pulley is specified with SPB profile, diameter 450 mm and 4 grooves. In addition, the taper-lock type TL. 3535 must match the bushing to be used on the shaft. Also check the belt length, axle distance and space conditions in the machine so that the pulley can be mounted correctly and work without unnecessary wear.

If in doubt, the old pulley should be measured and compared to the specified data. This reduces the risk of choosing a pulley with the wrong profile, wrong number of grooves or a taper-lock bushing that does not fit the shaft.

Brief summary

In summary, V-belt pulley SPB 450-4 - TL. 3535 is a pulley for V-belt drives, where SPB profile, 4 grooves and TL. 3535 are the most important data to match against the existing machine.
