Nf Series Roller Type Freewheel Bearing Description of Nf Series Roller Type Freewheel Bearing Type NF is a roller type freewheel non-bearing supported. Bearings are required to support axial and radial loads. Lubrication and sealing must also be provided by the installation. Standard lubrication is oil. Nominal outside diameter is a standard ball bearing dimension. A typical arrangement is to install this type alongside a bearing with the same housing tolerances, as shown on the following page. The inner race is keyed to the shaft. The outer race has a positive n6 tolerance to give a press fit in a H7 housing. Additional side notches provide for positive torque transmission. If the housing tolerance is to K6, use of the notches is not necessary, but the housing must be strong enough to not expand after assembly. Parameter sheet of Nf Series Roller Type Freewheel Bearing

CATSU excavator rake is a heavy-duty attachment that is designed to be mounted onto the end of an excavator's arm.
It is typically made of strong, durable materials such as steel or aluminum and consists of a series of tines or teeth that are designed to dig into the ground and grab onto rocks, tree stumps, and other debris.
The rake is used to clear land, remove unwanted vegetation, and prepare sites for construction or excavation work.
It can also be used to sift through soil and debris to separate out larger rocks and other materials. Excavator rakes come in a variety of sizes and configurations to suit different types of excavators and applications.
