Knobs, ball knobs, spherical knobs from°norelem
The norelem range comprises high-quality knobs, ball knobs and spherical knobs which are used as key operating elements in standard parts systems. They are predominantly used in machine construction for gripping, holding, securing or adjusting assemblies, machines or equipment.°
This overview is intended to present the product range, answer any questions you may have and help you choose the right product.
What is the difference between knobs, ball knobs, spherical knobs and mushroom knobs?
The various product categories can be distinguished as follows:°
Knobs°are a generic term used for fundamental components in machine construction used for manual operation and adjustment. They are used for e.g. clamping and unclamping fixtures, positioning and precise manual adjustment of machine parts.
Ball knobs°are a special type of knob that are ball shaped and are used for the manual adjustment on machines and assemblies. Their shape means they fit particularly well in the hand and enable even force transfer. They are usually made from plastic or metal.°
Spherical knobs°are also ball shaped operating elements, usually made from plastic and metal. They usually have an internal thread or a threaded pin for fastening and are used in fixture and machine construction. Compared to ball knobs, spherical knobs place even greater emphasis on ergonomic handling, making them even easier to grip.
Mushroom knobs°are characterised by their mushroom-like shape, which makes them particularly comfortable to hold. Their design makes them easy to use and prevent slipping, making them suitable for frequent manual operation.
An overview of the knob, ball knob, spherical knob and mushroom knob range: Flexibility in colour, material and more
The norelem range is characterised not only by the diversity of these products, but also by the various versions in which the respective knobs are available. Most products are available in a range of colours, including ball knobs in silver, light grey, colza yellow, pure orange and black-grey. The material and thread type can also be selected flexibly depending on the product.
Knobs, ball knobs and mushroom knobs°
The simple knobs from°norelem° are characterised by a flat top. They are available with a black oxidised finish and with either internal or external threads. Ball knobs and mushroom knobs are also available in various versions. They are made from steel, stainless steel or aluminium depending on the type, some are made from plastic which improves grip. The main focus here is on comfortable haptics, which ensures even force transmission by manual operation.
Spherical knobs°
At°norelem,°spherical knobs are characterised by a particularly non-slip grip achieved by serrations around the circumference. This eases the adjustment and operation machines and assemblies.
Spherical knobs with screw, optionally revolving
At°norelem° both revolving and fixed spherical knobs are available. Revolving spherical knobs°feature a freely revolving ball and are suitable for applications requiring frequent adjustment. Fixed spherical knobs°are used when a fixed positioning is sufficient. Spherical knobs are usually made from black-grey thermoplastic combined with a steel or stainless steel bush or threaded pin. So they are available with both internal and external threads.
These threaded inserts are available in a choice of steel or stainless steel. Spherical knobs with steel inserts offer impressive stability and are particularly suitable for general applications in machine and fixture construction. Spherical knobs with stainless steel inserts on the other hand, also offer high resistance to corrosion and are therefore particularly suitable for damp environments or applications involving cleaning agents.
The range of thread sizes and the option of internal or external threads means that spherical knobs can be flexibly integrated into various machine and equipment designs.
Thermoplastic ball knobs with thread
The ball knobs with internal thread are suitable for applications where a secure fastening is required. The long thread length permits these ball knobs to be fitted to more specialised constructions.
At°norelem°ball knob made from thermoplastic°are characterised by light weight and good durability. Thermoplastic ball knobs are suitable for applications involving frequent manual use, as they are comfortable to hold whilst also being robust and easy to maintain.
Metal ball knobs stand out with their convincing optics and versatility in machine and plant construction. At°norelem°these variants are available made from both aluminium and stainless steel.
The importance of material: Metal or plastic ball knobs?
The choice between metal or plastic ball knobs depends on the specific application.
Plastic ball knobs are lightweight and have pleasant haptics. This option is particularly suitable for applications involving lower mechanical loads or frequent manual operation, as they fit comfortably in the hand. They also offer good corrosion resistance and are available in a range of colours.
Metal ball knobs – stainless steel or aluminium at°norelem°– are significantly more robust and durable under high loads. They offer greater mechanical strength and are primarily used in industrial applications involving higher forces. Stainless steel ball knobs also offer high corrosion resistance and are therefore suitable for demanding environments. In addition to the increased durability, metal ball knobs impress with high-quality optics.
The wide range of mushroom knobs from°norelem
At°norelem, the mushroom knobs category offers the widest selection of knobs with a wide variety of designs available e.g. made from various materials such as stainless steel, thermoset and other plastics. In addition, these products are available with either internal or external threads.
Furthermore, anti-static mushroom knobs, mushroom knobs with caps, mushroom knobs with high and low collars and mushroom knobs with rounded heads are also available.
Applications for knobs and spherical knobs
Knobs, ball knobs, spherical knobs and mushroom knobs are used primarily in machine and equipment constructions. They are°essential°for the manual operation, adjustment, positioning and securing of machine components and assemblies.
Typical applications include clamping and unclamping fixtures, adjusting guides and stops, or operating machine covers and technical equipment.
Generally speaking, factors such as ergonomics, load-bearing capacity, corrosion resistance and ease of use play a decisive role in the selection process.
The appropriate knob from°norelem
The°norelem°range offers all suitable types of knobs, ball knobs, spherical knobs and mushroom knobs. The range of different materials, sizes, colours and versions available make these products suitable for many individual requirements.
Be it ergonomic mushroom knobs for frequent use, robust stainless steel ball knobs for demanding environments, or ergonomic spherical knobs for comfortable operation,°norelem°offers the appropriate solution for your application.
