K33 Monolithic Caster

Product Description:

By using two raceways, the K33 series Monolithic caster improves the strength of the caster dramatically by heat treatment of both the raceway and yoke. The yoke is stretched and molded so that it not only strengthens it but also makes the rotation flexible, so it can be used for powered traction.

Advantages:

Structural Advantages:

The K33-series industrial monolithic wheel is featured with an ultra-thick 5.5mm top plate and 4mm bracket, together with a 19mm center pin, which is riveted hydraulically provides a very sturdy structure. The single-wheel load capacity is up to 600kg, thus it can effectively withstand impact loads.

Double Raceway Heat Treatment Technology Advantages:

The swivel head incorporates a double raceway design, and both the raceway and the bracket receive a rigorous heat treatment hardening process. This results in an increase in overall strength, as well as a decrease in starting resistance.

Precision Bearing Guarantee:

Precision sealed ball bearings are a standard feature in the product, which are highly effective in preventing the entry of dust and debris, the speed of the wheel is minimally impacted, and the servicing interval is extended.

Professional Selection Advice:

To select the most suitable K33 series casters, you may refer to the selection logic that is derived from the table data below:

Step 1: Select the specifications based on the load

Medium to Light Load (400-500kg): If the load per wheel is not more than 500 kg, it is advisable to pick a 3-inch (76.2mm) or 4-inch (101.6mm) wheel size. The total height of the installation is lower here (120mm-140mm), hence a more stable center of gravity is achieved.

Heavy Load Requirements (550-600kg): For a load of 600kg, make sure that you pick the 6-inch (152mm) or 8-inch (203mm) sizes. Larger diameter wheels not only have a higher load capacity but also better passability, easily overcoming small obstacles on the ground.

Step 2: Select Wheel Material Based on Ground Surface and Working Conditions

Choose UD (Aluminum Core Polyurethane): Heavy industrial floors, such as automotive manufacturing and aerospace, etc., are the main applications for this product. The aluminum core performs a rapid heat dissipation, thus it is capable of withstanding higher moving speeds and mechanical traction.

Choose SE (High-Elasticity Elastomer): Electronic workshops, medical equipment facilities, or laboratory environments that require a high level of quietness and shock absorption are the best applications for this product.

Step 3: Verify Installation Dimensions

The Standard Installation (Version 01): Top plate dimension is 114×100mm, and the hole spacing is 92×66.5mm. This is the most common standard size.

The Enlarged Installation (Version 02): The top plate has a dimension of 160×116mm and the hole spacing is 122.5×64.5mm. Version 02 should be the choice if a bigger load-bearing area is needed, or the present large casters are being replaced.

Step 4: Functional Configuration

If braking is needed: "+IS" (top plate brake, note: the braking version increases the installation height by 21mm) or "+DT" (front brake) should be added to the model number depending on the brake type.

Frequent Turning: It is suggested to do regular lubrication of the raceway to get the maximum output from the double heat-treated ‍‌raceway.

Note: For swivel models, suffixes come with "+IS": Top Plate Brake, which increases the height by 21 millimeters, "+DT": Front Brake.

Application Areas：

Trolley、Tool cart、Automobile manufacturing industry、Storage cage、Tractor、Aerospace industry.
