How long do skateboard bearings last


Other than brackets, skateboard wheels are perhaps the most resilient skateboard gear accessories. Hardware such as plates, sandpaper, bearings, and bolts must all be replaced periodically, but wheels can frequently be used for an extended period of time. You need skateboard bearings in order to skate comfortably. It significantly impacts how slick the skateboard is because it is a component that is attached to the rotating shaft of the wheel. However, there aren't many visual differences between the products, so many customers might be unsure which one to pick. I will now discuss how to choose skateboard bearings as well as some suggested products. Please have a look if you are thinking about buying skateboard bearings.

Types of bearings.

There are two types of skateboard bearings: oil type and grease type.

Features of oil type

• Faster rotation than grease type

• Regular maintenance required

• Long-lasting if maintained

Basically, oil type bearings are common. Maintenance is a hassle, but regular maintenance will give you the best possible slip.

Features of grease type

• Rotation is slower than oil type

• Semi-permanent grease for maintenance levitation

• If the rotation gets worse, it needs to be replaced.

Grease type bearings are not widely available, but those who say "maintenance is troublesome" should choose grease type bearings.

What are bearings?

A bearing is an object that tou can on your skate trucks and that transfers loads to a frame from the spinning shaft it supports, utilizing rolling elements (such as balls) contained between two rings with grooves. rolling to enable it to rotate so you can turn right and left with your skateboard. The rolling elements display negligible rolling resistance and almost no slide due to the relative movement of the grooves. They are unique components that increase your skateboard's comfort and speed. A metal ball with excellent dimensional accuracy is integrated into the bearing's structure. In order to move smoothly, the ball rotates to reduce friction.

A big stone block perched atop a stack of logs laid on the ground is one of the earliest and best-known rolling element bearings. The friction that would be caused by dragging the stone directly over the ground is avoided since the stone is pulled by the logs, which roll along the ground with little slide. Each log emerges from the back, goes to the front, and is then rolled back onto the block.

A shaft is fitted into a hole that is bigger than its diameter to create a swivel bearing with rolling elements. A series of cylinders known as "rollers" are then used to fill the space between the shaft and the hole all the way around. When the shaft rotates, each roller behaves like the logs in the previous example. The rollers are never out of alignment, though, because the bearing is spherical. Bearings are components that, depending on their quality, have a significant impact on the life and operation of machinery. They are typically mounted on the rotating shafts of industrial equipment and casters. Even with skateboard bearings, the propulsion force increases with performance, so even a tiny force can cause the skateboard to slide.

The advantage of using bearings is that they offer a good compromise between several aspects, like price, size, weight, load capacity, durability, precision, or the consequent friction. Although fluid bearings can occasionally simultaneously combine load carrying capacity, durability, precision, decreased friction, high rotating speed, and sometimes an acceptable cost, different designs may be superior for a specific application but worse in most other circumstances. Only plain bearings are employed as frequently as roller bearings, which are widely used in standard mechanical parts for several applications in the marine, aviation, industrial, and automotive sectors. Given their significance, they have evolved into core modern technological items.

Bearings are typically made an extremely hard but quickly oxidizable chromium steel with a 1% carbon and 1.5 % chromium content. In order to increase hardness and wear resistance, manganese (Mn) and molybdenum (Mo) are added to other steels. High alloy steels are used for applications in corrosive environments. The latter can be applied to the human body as well, at least temporarily. Hardenable steels only see gradual increases in corrosion resistance over time; they are never truly "stainless".

There are bearings for special operating conditions:

  1. Made of stainless steel for use in harsh environments.
  1. Two-material, where the bearing rings are made of steel and the rolling elements are made of ceramic (silicon nitride or zirconium dioxide), for example in bearings for machine tool spindles.
  1. Ceramic bearings where both the bearing rings and rolling elements are made of silicon nitride, zirconium dioxide, or silicon carbidePlastic bearings with glass or ceramic rolling elements resistant to aggressive acids or alkalis in the chemical and food industry.
  1. Bearings with plastic cages for quiet operation.
  1. Bearings with a current-insulating coating on the outer or inner ring, in order to prevent unwanted current flow through the bearing and thus damage caused by electrical corrosion, such as when using converters of frequency to control the speed of three-phase motors.

Do skateboard bearings expire?

Although bearings are insulated, packed, and coated with an anti-corrosion substance, exposure to the surrounding air cannot be totally avoided. Do not expose bearings to dampness or moisture when storing them; keep them dry. The efficiency of anti-corrosion protection varies depending on the warehouse's environment. It typically lasts between one and four years. Bearings may be kept safe for up to 10 years by storing them in a variety of unique ways. For instance, to stop corrosion, bearings can be submerged in a tank of turbine oil.

How do I know if I need new skateboard bearings?

If after cleaning and relubricating your bearings, they still won't spin, replace them. If bearing shields or ball bearings are missing, replace them right away to avoid blocking and accidents. However, there's still a chance you can save them. Before you go out and get a new set, here's what you should do to keep them in good condition and clean them.

How long do they last?

Your bearings should survive at least a year or two of casual skating, if not longer, assuming you avoid skating in the rain. If you do skate in the rain, be sure to routinely clean your bearings. Pack your bearings out with heavier grease for even greater defense against the rain and muck from the road.
