Roller Guide for rolling mill are a series of rollers that determine the angle and direction of the steel as it is guided through the rolling mill to the mill roll.
What is guide roller in ship?
Marine guide rollers are used to safely change the direction of the mooring rope. They can work together or separately. We produce standard and non-standard productions for you.
What is cross roller guide?
The Cross Roller Guide is a limited stroke linear guide that has precision rollers orthogonalized alternately. This product provides rigid yet supple linear motion and is particularly suitable for linear guidance where high rigidity and supple movement is demanded.
What is pedestal roller?
The PM-5090 Pedestal Roller is a high-quality, portable outfeed table for your machines, including table saws, drill presses, and other shop machines. This affordable tool makes it easy to complete your shop.
What is a Panama fairlead?
A non-roller type fairlead mounted at the ship’s side and enclosed so that mooring lines may be led to shore with equal facility either above or below the horizontal.
What does a roller bearing do?
Roller bearings — also known as rolling-element bearings — are similar to ball bearings in that they are designed to carry a load while minimizing friction. However, roller bearings transmit loads using cylinder rolling elements, rather than balls, to maintain the separation between moving parts of the bearing.
What is a crossed roller bearing?
Crossed-roller bearings are bearings for high-precision applications whose dimensions conform to ISO dimension series 18 as per DIN 616. They comprise outer rings, inner rings, rolling elements and plastic spacers. The outer ring is split and is held together by three retaining rings.
What is crossed roller slides?
Crossed roller slides and tables are linear bearings that use cylindrical rollers — as opposed to balls — to carry a load. In these mechanisms, also known as crossed-roller bearings, cylindrical rollers are sandwiched between two parallel guides called the table and bed.
How do you clean an Aftco roller guide?
After removing the pins and screws (using a #2 standard screwdriver on each side of the guide or top), all parts, including the inside of the frame, should be wiped clean with paper towels using a mild solvent or thinner.
What is close chock?
Closed Chocks are used for holding down line or wire by running it through the center of the chock. They secure line or wire close to the deck and eliminate the line or wire from “riding up” on a bitt.
What is high pedestal?
: to think of someone as a perfect person with no faults : to admire someone greatly Her boyfriend placed her on a pedestal.
What is deck fittings?
For boaters, deck fittings refer to pieces of hardware. These metal pieces are used to secure various items to the deck, including fishing rods, ropes and rigging, tarps and sails, railings, life preservers and steering wheels.
What is a chock on a ship?
Chocks: are structural reinforcements on ships which guide the mooring lines to and from the shore / other vessels. Chocks need to be of a much higher SWL than the mooring line to avoid structural damage and withstand various forces when a vessel is moored.
What is Bollard in ship?
In the maritime contexts in which the term originates, a bollard is either a wooden or iron post found as a deck-fitting on a ship or boat, and used to secure ropes for towing, mooring and other purposes; or its counterpart on land, a short wooden, iron or stone post on a quayside to which craft can be moored.
What is starboard quarter?
Starboard Quarter: The starboard surface of the vessel’s hull that is located behind the beam is called the starboard quarter. Aft: Anything at, near, or toward the stern of the boat is considered to be aft. Ahead: Anything in front of the boat, including objects or a destination, would be considered ahead.
What is the difference between bearing and baring?
As present participle verbs, remember that “bearing” means “to bear,” “baring” means “to bare,” and “barring” means “to bar.” Barring these usages, remember that “bearing” can also be used as a noun and “barring” as a preposition.
Which is better roller bearing or ball bearing?
As a general rule, ball bearings are used at higher speeds and lighter loads than are roller bearings. Roller bearings perform better under shock and impact loading. Ball bearings are usually sold as assemblies and are simply replaced as units.
Why are bearings used?
Nowadays, bearings are one of the most commonly used machine parts because their rolling motion make almost all movements easier and they help reduce friction. Bearings have two key functions: They transfer motion, i.e. they support and guide components which turn relative to one another. They transmit forces.
What is a ring bearing?
A slewing bearing or slew[ing] ring (also called a turntable bearing) is a rotational rolling-element bearing that typically supports a heavy but slow-turning or slowly-oscillating loads in combination (axial, radial and moment loads), often a horizontal platform such as a conventional crane, a swing yarder, or the
What are the advantages of linear cross roller bearings?
Crossed roller bearings provide more accuracy, rigidity, and weight-bearing capacity for linear motion than other commonly used friction-reducing devices such as ball bearings. And unlike ball bearings, they can support moment loads, radial forces or tilting loads.
Can you cast with roller guides?
ROLLER TOP WILL CAST JUST FINE. I’VE USED LIGHT RODS WITH ALL AFTCO ROLLERS (NOT EVEN THOSE LIGHT GRAPHITE ONES) AND THEY CAST WONDERFULLY!…. SO YES, GIVE THE GUY WHAT HE WANTS.
