Soil compaction occurs when soil particles are pressed together, reducing pore space between them (Figure 1). Heavily compacted soils contain few large pores, less total pore volume and, consequently, a greater density. A compacted soil has a …
High-precision vertical motion is achieved using a direct vertical guiding system composed of matched pairs of anti-creep crossed roller bearings for the GTS30V and recirculating ball bearings for GTS70V. These linear guides were chosen to provide the straightest trajectory, smooth and precise motion and robust, long term operation.

Corrosion-Resistant V-Groove WheelTrack Casters with Polyurethane Wheels. The wheels of these casters have a 90° V-groove and a flat tread to move your equipment on angle-iron track as well as the floor. Polyurethane wheels combine the abrasion resistance of plastic with the shock- and sound-absorbing qualities of rubber.
Sanitary Shaft-Mount V-Groove Track Rollers. Support and guide loads on angle rails in food, pharmaceutical, and other sanitary environments. Also known as yoke-style cam followers, these track rollers offer more mounting flexibility than threaded alternatives and are typically mounted on shafts and clevis rod ends.
Lead screws are better for vertical applications. Lead screws are generally less efficient, requiring greater torque and a larger motor and drive. Lead screws have higher friction and run a hotter temperature. Most lead screws are not well suited to high throughput, high speed applications or those with continuous or long cycle times.
Controlling every facet of manufacturing at one location helps us minimize lead-times and maximize quality. All Columbia Steel parts are American made and …
Roller fairlead. Roller fairlead saves the cable from getting damaged by sharp borders. They are used with steel cable winches. They use two vertical mounted rollers and two horizontal mounted rollers to guide the steel cable from a different angle. Almost every steel-cable winch you buy today will come with a steel roller fairlead.
When moving an object with a mass of 500 kg using a screw with an effective diameter of 33 mm and a lead length of 10 mm (lead angle: 5°30'), the required torque is obtained as follows. Rolling guide (μ= 0.003) Ball Screw (from μ= 0.003, η= 0.96) Frictional resistance on the guide surface Driving torque Fa=0.003×500×9.8=14.7N
Here's a very simple vertical blind diagram…. This diagram is that of a 3 1/2″ vertical blind with standard features. Note its essential parts and names, as this is how they are most commonly known. This type of blind may vary greatly in materials used, but its basic parts and functions are the same. In this article we will examine these ...
Needle roller bearing is a special type of roller bearings that has cylindrical rollers that resemble needles because of their small diameter. Normally, the length of rollers in roller bearings is only slightly more than its diameter. When it comes to needle bearing, the length of rollers exceeds their diameter by at least four times.
Lead screws are often used in linear actuators and positioning equipment to provide thrust (axial) force to drive a load. The amount of axial force that a lead screw assembly can withstand is determined by the diameter and lead of the screw and the material of the nut — plastic or bronze.
In order to reduce the larger pressure resistance (pressure difference between inlet and outlet) of a vertical roller mill, the flow field in the vertical roller mill is numerically simulated by CFD technology. Based on the simulation results, the reasons that led to the larger pressure resistance of the vertical roller mill is studied, offering the theory guide for the technology of reducing ...

Lead. Lead is the linear travel the nut makes per one screw revolution and is how ball screws are typically specified. The pitch and lead are equal with single start screws. For multiple start screws the lead is the pitch multiplied by the number of starts.
Cable Rollers. Cable Rollers | Pulling Cables into Trenches. Cable rollers are used to support and guide LV, MV & HV cables into open trenches without damaging cable sheaths and incurring overbending stresses on power cables, typically at LV (1000 volts), MV (11kV/33kV), HV (66kV) and EHV (132kV-400kV) voltages.. Heavy duty cable rollers with zinc plated steel frames are …
A roller-coaster car has a mass of 1200 kg when fully loaded with passengers. As the car passes over the top of a circular hill of radius 18 m, its speed is not changing.
