Ball bearing was the response to reduce this friction and it does this job extremely well. However, the small contact surface of the balls, which reduces the friction so much, is also their biggest weakness i.e. the point loading of the balls can lead to compression, at high loads and the block jamming. Ball bearing is high performance block suited to running at high speeds, but it´s size and weight increases significantly as loads rise. So, the R+D for block bearings wasn’t finished at this stage.

Save money on replacing your bearings with the greaser tool that makes it easier than ever to grease your bearings WITHOUT removing the axle.

Found on sailing boats of 35’+, these blocks are optimal for mainsheets, guy leads, backstays, after guys and tack lines.

Small spherical balls have little contact between surfaces, resulting in low friction. However, ball surfaces can be deformed under heavier loads, resulting in the jamming of the block.

Although the name itself sounds quite vague, these are smooth, solid surfaces that move across each other. The sheave rotates across the central hub.

For larger boats, blocks use a blend of ball bearing and roller bearing. Roller bearing takes the main line loads, leaving the ball bearing mounted around either edge to keep the sheave running smoothly, even with off-axis loads. This can be seen in the ‘2-Stage bearing system’ of the Ronstan Core Blocks.

This is merely a modern evolution of the plain bearing block, but it has sparked furious debate: is it a real block or just a friction sheave?

Roller bearing was the compromise between plain bearing and ball bearing. Roller bearing facilitates low friction at high working loads. Heavily-loaded lines run faster, smoother and are more easily adjusted compared to a plain bearing block. They can also be smaller and lighter than a ball bearing block, for the same working load, due to the increased contact between the rollers and the hub.

Metal or plastic sheaves roll directly on metal pins or bushings. Plain bearing is often comprised of a plastic surface and a metal shell. Another common kind of plain bearing will use a soft bronze bushing and a polished steel shaft. Their static and high-load capability make plain bearings suitable for vangs, backstay, runner and halyard turning blocks. However, full contact between two surfaces results in more friction, reducing their potential running speed.

What makes Cooper's split bearings the smart choice both for engineers and for business is their flexibility compared to solid bearings.

The earliest (and original!) blocks used plain bearings, but they have slowly given way to higher-performing bearings. Plain bearing has the least number of moving parts. A long lifespan and low maintenance with heavy load applications are the main benefits of plain bearing.

For many years, the backbone of most block ranges were heavy plastics with aluminium or stainless steel structural side plates, which were used to transfer loads. As computing power advanced, designers modelled crucial load paths accurately to ensure sufficient strength from modern, lightweight composite materials. Today, blocks are lighter and smaller than those used a decade ago, making them perfect for the thinner hi-tech lines / ropes.

In this blog post, we discuss types of existing bearings: ball bearing, plain bearing and roller bearing. Deck blocks are evolving. Bearings are constantly improving, as manufacturers endeavour to minimize friction in different load cases. Apart from number of sheaves, blocks can also be categorised by their bearings.

‘Rollers’ are small tube  arranged  around the centre of the bearing. Rollers are a ‘compromise’ between the plain and balls. Rollers wear  faster than ball bearings, but can carry higher loads as they have a higher contact area.
