OVERVIEW

Precision Replacement Component

The Walter 48Q074 Ball Bearing is a high-quality replacement component designed to restore the functionality of Walter Surface Technologies power tools. Identified by the industry-standard designation 608 2Z and manufactured in accordance with DIN 625 specifications, this deep groove ball bearing is engineered for precision, durability, and high-speed performance. It serves as a critical mechanical interface, facilitating smooth rotational motion while supporting radial and axial loads within the tool's assembly.

The "608" classification denotes its specific dimensions: an 8mm inner diameter, a 22mm outer diameter, and a 7mm width. These dimensions make it one of the most versatile and widely used bearing sizes in compact industrial machinery and power tools. The "2Z" suffix indicates that the bearing is equipped with metal shields on both sides. These non-contact shields are essential for preventing the ingress of dust, metal shavings, and other particulate matter common in grinding and finishing environments, while also retaining the pre-filled grease lubricant inside the race.

Using genuine OEM parts like the 48Q074 ensures that the replacement fits perfectly without play or misalignment, which is crucial for maintaining the balance of high-RPM tools like angle grinders and sanders. Improper bearings can lead to excessive heat generation, noise, and premature failure of the tool's motor or gear assembly. This bearing is pre-lubricated for life, requiring no additional maintenance upon installation.

Technical Specifications

This bearing is constructed from high-grade hardened steel to withstand the stresses of continuous industrial use. The DIN 625 standard ensures consistent tolerances and clearance classes, providing reliable operation under varying thermal conditions. Whether used in the armature, spindle, or fan assembly of a Walter tool, this component delivers the smooth operation required for precision surface finishing tasks.

FAQ

The 48Q074 is a standard 608 series bearing with an Inner Diameter (ID) of 8mm, an Outer Diameter (OD) of 22mm, and a Width of 7mm.

The '2Z' (or ZZ) designation indicates that the bearing has metal shields on both sides. These shields protect the internal components from dust and debris while retaining the lubricant.

Yes, the bearing comes pre-packed with the appropriate amount of grease for its service life. You do not need to add lubricant before installation.

While it is sold as a genuine Walter replacement part, the 608 2Z is a standard industry size used in many brands of power tools, skateboards, and electric motors. However, for Walter tools, this specific SKU ensures OEM quality.

2Z bearings have metal shields, which are non-contact and allow for higher speeds with less friction. 2RS bearings have rubber seals that provide better sealing against moisture but create more friction and heat.

Signs of a bad bearing include unusual noise (grinding, squealing), excessive vibration, the tool feeling hot to the touch near the bearing area, or the shaft having play/wobble.

This part is compatible with various Walter Surface Technologies power tools. Please check your tool's parts diagram or manual to confirm the bearing size or part number 48Q074.

Deep groove ball bearings like the 608 series are designed primarily for radial loads but can handle moderate axial (thrust) loads in both directions.
