Think of all the reasons you love – or maybe just respect in a professional sense – roller chain. Now double that. That’s some of what you can do with double strand roller chain. Double roller chain is just what it sounds like: two strands of roller chain connected side by side into a single […]
The main thing to know about finished bore sprockets is that they come with the keyway already machined into the bore, and with the set screw to secure the sprocket to the shaft. But is there anything you need to know about the keyway? Shafts and sprockets work together via a keyed joint. The key […]
For some projects, the choice between a chain drive and a belt drive will be pretty clear-cut. On others, you’ll work through the pros and cons of both and no obvious winner emerges. Let’s go through some of the factors in the chain drive vs. belt drive discussion. System speed and ratio Belt drives are […]
“This bearing’s running a little hot.” We’ve all heard that, and we’ve probably all had the same response: “OK, but you’re going to need to give me a little more than that. Which pillow block bearing, and how hot?” There’s no point in checking temperatures if we don’t have a good idea of the normal […]
Let’s head over to our Bushings page and pick up a taper-lock bushing. We’ll grab the #1108×11/16”. What did we just pick up? The name of a taper-lock bushing tells you most of what you need to know. The four-digit number at the start is the “bushing type” and gives you two pieces of information. […]
QD stands for Quick Detachable and a QD bushing features a flange that connects the bushing (quickly!) to the sprocket. They also have a taper – usually 4 degrees, half that of a taper-lock bushing – that, along with the cap screws, provides a closer fit. How to Install a QD Bushing Installing a QD bushing […]
From the farm to the grocery store checkout, the food supply chain moves along one conveyor belt after another. Conveyor belts in the food industry have many different applications, each with their own technical requirements and involving regulatory compliance and engineering best practices. Quite a lot for something as “simple” as sending your carton of […]
Chain size, type, number of teeth, and bore size are all you need to select the correct roller chain sprocket. When you look at sprockets on a product page or catalog, you’ll see a string of numbers and letters. Let’s break one down. #50BB15x1/2” is one of the seventeen idler roller chain sprockets currently available […]
A taper-lock bushing gets its name from the 8 degree taper from one side to the next before it locks into place. This reduces the necessary length-thru-bore for any application. An internal screw holds the taper-lock bushing in place, providing a slimmer fit than a flanged bushing. First, what not to do when installing a […]
Pillow block bearings support shafts that run parallel to the mounting surface. This makes them a very simple but vital part of conveyor systems, industrial fans, farm equipment, jib cranes, car washes, and much more. With that much at stake, let’s make sure you get the right one and use it the right way. Split […]
