Manual knockout sets with unique 3-point cup cutting surface provides a clean, quick and easy cut, saving time and money.
Slug splitting punch features in an economic Manual ball bearing design.
Cuts through 10 gauge mild steel as well as aluminum, fiberglass, and plastics.
Punches and Dies may be used with southwire mpr01sd ratchet drivers and mp-01pro or m360hp Hydraulic drivers.
Ball bearing 7/16-inch and 3/4-inch draw studs for reduced friction.

This A-Type, angular contact ball bearing is best suited to applications with high axial loads. This bearing also works well in radial or combined radial-thrust applications but should never be used alone to support moment loads or reversing axial loading..
Thoroughly coated in MIL-PRF-3150 or MIL-PRF-6085 oil and drained of excess and vacuum sealed in a plastic bag for shipping..
Manufactured to ABEC 1F precision tolerances related to the bearing bore, outer diameter, radial runout, axial runout and radial play..
Static Thrust Rating 970 pounds, Dynamic Thrust Rating 960 pounds.
This RBC thin section ball bearing can be advantageous in a design where space limitations, combined loading, or weight restrictions are proving to be challenging to overcome with a traditional ball bearing solution..

Design revolves around a "floating" center rod that moves as you pick up balls, eliminating bent wires.
Includes a stand option that allows you to swing the handles down, raising the basket to waist level for ball access, and swing the handles up, lowering the basket for ball pick up. Unbreakable basket bottom is constructed without welds.
Basket assembled at the factory prior to shipment - for added protection along the entire contact points (not just at corners like other ballhoppers).
Comes shipped in four pieces A)The Basket B) The two Handles C) the cover!.
#1 top of the line tennis hopper and truly built like one should be! GUARANTEED DURABILITY! Will outlive any other hopper.

Low friction: The ball does not cycle and can achieve rolling motion with minimal friction..
High precision linear movement: as part of shaft and nut, the clearance in rotation direction can be adjusted to ensure accuracy..
Transferable rotating torque: the ball rolls on the ball groove of the spline shaft and moves in a straight line while transferring the rotating torque..
Compact design: even a single shaft mechanism can move in a straight line, while keeping the nut in the direction of rotation without deviation..
Large bearing capacity and long service life: Because the rolling surface adopts r-shaped ball groove matching with the ball diameter, the contact area is large, the bearing capacity is strong and the service life is long..

Cartridge block with ball bearing insert for use with cylindrical bore housings.
Steel cartridge housing and single-row radial ball bearing for applications that support high radial loads.
Relubricatable solid one-piece cartridge housing for maximum strength and rigidity.
Fixed-type bearing with two set screws set apart at 120 degrees for secure attachment to a cylindrical shaft.
Felt labyrinth seal for protection against contaminants, and for less drag and heat generation than heavy contact seals.

【16PCS Bearings + Caps Set】 Includes 16x MR137 precision high-speed ball bearings with blue plastic seals and 16 pairs of ball bearing caps in four bright colors (diameter: approx. 2.1cm). MR137 Steel Ball Bearing size: I.D. (inner diameter) =7mm, O.D. (outer diameter) = 13mm, Thickness: 4mm..
【Premium Quality】 The bearings are made of high-quality stainless steel and plastic for durability and deformation resistance under heavy loads. Inner and outer races are machine polished for smooth, high-speed rolling. This bearing provides higher speeds, precision, and durability, reducing replacement and maintenance costs..
【Radial Ball Bearings】 MR137 bearings are sealed on one side to protect the equipment against contaminants such as dust and water and retain lubrication. Stainless steel races ensure durability and corrosion resistance. Single row radial ball bearings support applications with radial and axial loads..
【Wide Application】 Caps made with ABS plastic are lightweight and durable, compatible with MR137 bearings. With easy-to-install components, this bearing is perfect for a wide variety of applications, including fidget spinners, skateboards and other DIY projects. Use as replacement when the original caps and bearings are lost or ....
