V-belt pulley SPZ 250-2 - TL. 2012 – pulley for V-belt drive

V-belt pulley SPZ 250-2 - TL. 2012 is an SPZ V-belt pulley for taper-lock mounting, intended for belt drives where a V-belt is to 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 SPZ profile is typically used in compact belt drives where a narrow V-belt profile and stable power transmission in limited space are desired.

What is this V-belt pulley used for?

With two grooves, the pulley can be used in belt drives, where two V-belts work in parallel to distribute the load more evenly. The product is relevant both for new constructions and for replacement in existing systems, where the profile, diameter and taper-lock must match correctly. A V-belt pulley is also called a pulley, V-belt pulley or belt pulley, and the right combination of belt and pulley is crucial 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. 2012, 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: SPZ
• Diameter: 250mm
• Outer diameter (Da): 254mm
• Effective diameter (Dw): 250mm
• Number of grooves: 2
• Taper lock: 2012
• Material: Cast iron
• Suitable for: V-belt drive with SPZ profile
• Crown width (b2): 28mm
• 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 SPZ profile, diameter 250 mm and 2 grooves. In addition, the taper-lock type TL. 2012 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

This V-belt pulley is therefore particularly relevant when you need a metal SPZ pulley for a belt drive with a taper-lock bushing and a number of grooves that matches the desired load.
