Selection of guides for stamping dies


Steel guide bushes TSR / TSD / TSK

Steel guide bushes may be used everywhere high and especially lateral force appear. Due tu high friction on contact surfaces this type of guiding is recommended in applications where speed doesn’t exceed 20m/min. The bushes require constant lubrication. Grease or oil can be supplemented to spiral grooves through a grease nipple located on the sleeve flange.

Guide bushes with bronze inserts TBR / TBD / TBK / BEB

Guide bushes with bronze inserts are composed of a steel external sleeve with centrifugally casted bronze insert. The insert has spirally made grooves to ensure constant and even distribution of grease, which can be supplemented through a grease nipple located on the sleeve flange. Thanks to the centrifugal casting process, the bronze layer is thick enough that even in case of high wear the steel part doesn’t come in contact with the guide pillar, preventing it from damage.

Self-lubricating guide bushes TGR / TGD / BUS / BGD

Self-lubricating elements are used wherever excellent sliding properties and a long life of the component are required. They work well both in rotary and in linear applications. The raw material used in self-lubricating parts is bronze or steel, which provide excellent mechanical properties, and graphite impregnated with lubricant. During the initial work stages, due to friction with the contact surface the lubricating agent releases gradually, creating a film which ensures slip in further cycles. Depending on type of the element, the graphite contact (sliding) surface amounts to between 25% and 35% of the total working surface. Under the recommended operating conditions, the self-lubricating components don’t require any maintenance.

Guide bushes with sintered ferrite insert TFR / TFD / BFD

Precision guide bushes with sintered ferrite insert are composed of an external steel sleeve with sintered ferrite insert tightly pressed in. The insert has a sponge-like structure with surface porosity up to 20%. At the final production stage the pores are being saturated with oil in vacuum chambers. Under the influence of temperature the oil gradually flows out creating a friction-reducing film. Additional lubrication is only possible with recommended lubricants. Using grease other than recommended causes pore-clogging. The guide bushes with sintered ferrite inserts can be successfully used in high speed tools and with extreme loads

Ball bearing guides TKR / TKD / TKP / TKK

Unlike the other types, in ball bearing guides the sliding friction phenomenon doesn’t exist. The movement resistance mainly results from rolling friction which is significantly smaller. Ball cages are made of a brass sleeve with balls firmly fitted in its cavities. Thanks to the appropriate guide and bush tolerances, a “preload” effect appears, eliminating any guiding clearance. Low friction and a lack of clearances recommend ball cages to be used every time when high precision and extreme speeds are required.
