wheels Ø140, Ø160, Ø200

wheels with a metal or plastic disk measure with a rubber hoop
wheels fitted with sliding bearings, some Ø160 wheels may have rolling bearings

Usage: simple, less loaded orbs. Ø160 wheels are used for stair treads, either with a sliding bearing (for smaller loads) or with a rolling bearing for heavier loads. The rolling principle of the trio of 160 wheels corresponds to the stair step standard = 160 mm.

wheels Ø200 P (N20 P)
Ø260 P (N26 P)
mantle 3.00 – 4

Inflatable wheels with plastic disc and sliding bearing. The most common type of wheel used for most mid-range loads up to 250 kg. With this more affordable type of wheel, it is necessary to respect the plastic disc, which absolutely requires compliance with the limitation of maximum inflation to a pressure of up to 150 kPa. If this restriction is not observed, the plastic trim will tear off. disc or changing the heel of the mantle and the destruction of the soul.

wheel Ø260 K (N26K)
mantle 3.00 – 4

Inflatable wheel with a metal disc, can have a sliding or rolling bearing. Optimum wheel diameter from the point of view of the mechanics of tilting heavy loads. It is used for loads with a maximum load of 250 to 300 kg.

wheel Ø260 K (S26K)

Bike with solid rubber rim with metal disc. Due to its high hardness, this wheel has very little rolling resistance. During operation, it is necessary to respect the fact that this wheel is absolutely "inflexible". Therefore, it is not able to absorb any impact on the edge or other unevenness. This impact on the edge leads to the destruction of the wheel by cracking in the longitudinal direction of the rim. (A solid rubber hoop is made by joining two lightweight moldings)

wheel Ø300 (N30K)
mantle 4.00 – 4

Inflatable wheel with a metal disc, equipped with a rolling bearing. The standard type of wheel used in most professional and special wheels.*

wheel Ø350 (N35K)
mantle 3.50 – 6

Inflatable wheels with a metal disc. The disc is strengthened by molding and connected by six screws. This wheel has either a wider standard hub using a rolling bearing and plastic plug or a reinforced hub and is assembled using twenty pieces of 4×45 steel pins. The use of this wheel is for the heaviest loads up to a maximum load of 350 kg.

Diameters of the axles of the wheels on which the wheels are mounted:

For wheels Ø140 and Ø160, the axle diameter is 15 mm. For all other wheels, with the exception of the reinforced Ø350 wheel, the axle diameter is 20 mm. For the reinforced wheel Ø350, the axle diameter is 22 mm. For most wheels, the size of the axle allows the use of both plastic and metal disc wheels. It can therefore be replaced with wheels with a metal disc for wheels equipped with plastic discs.
